Introduction

The Cisco ASR 1000 Series Aggregation Services Routers are the next generation Cisco midrange router products. The Cisco ASR 1000 Series Aggregation Services Routers use an innovative and powerful hardware processor technology known as the Cisco QuantumFlow Processor. The Cisco ASR 1000 Series Routers consist of three different routers: the Cisco ASR 1002 Router, the Cisco ASR 1004 Router, and the Cisco ASR 1006 Router.

•The Cisco ASR 1002 Router is a 3-SPA, 2-rack-unit (RU) chassis with one Embedded Services Processor (ESP) slot that comes with the Route Processor (RP), Cisco ASR 1000 Series Shared Port Adapter Interface Processor (SIP), and four Gigabit Ethernet ports built in.

•The Cisco ASR 1004 Router is an 8-SPA, 4-RU chassis with one ESP slot, one RP slot, and two SIP slots.

•The Cisco ASR 1006 Router is a 12-SPA, 6-rack-unit (RU), hardware-redundant chassis with two Embedded Services Processor (ESP) slots, two Route Processor (RP) slots, and three SIP slots.

For the single-route-processor Cisco ASR 1000 platforms, the Cisco ASR 1002 and Cisco ASR 1004, the Route Processor has a dual Cisco IOS Software option that allows these routers to use Cisco IOS software redundancy, Cisco high-availability features, Nonstop Forwarding (NSF), and In Service Software Upgrades (ISSUs). This option requires the Cisco ASR 1000 Series Route Processor to have 4 GB of DRAM memory.

The Cisco ASR 1006 Router supports fully redundant Route Processors that allow for full Route-Processor hardware redundancy, NSF, ISSU, and future Route-Processor service upgrades.

The Cisco ASR 1000 Series Routers run Cisco IOS XE Software and introduce a distributed software architecture that moves many operating system responsibilities out of the IOS process. In this architecture, Cisco IOS, which previously was responsible for almost all of the internal software processes, now runs as one of many Cisco IOS XE processes while allowing other Cisco IOS XE processes to share responsibility for running the router.

One of the key features of the Cisco IOS XE Software is support for dual Cisco IOS software consolidated packages in a single Route Processor for software redundancy in the 2-RU and 4-RU chassis systems. These dual Cisco IOS consolidated packages can consist of the same software consolidated packages for backup or different software consolidated packages for resilient upgrade.

Note Software redundancy is not supported on the 6-RU chassis.

The Cisco ASR 1000 Series Routers target both enterprise and service provider applications and provide application-specific features for broadband subscriber aggregation and network application services with improved processing performance and high availability.

For information on new features and Cisco IOS commands supported by Cisco IOS XE Release 2, see the "New and Changed Information" section and the "Related Documentation" section.

System Requirements

This section describes the system requirements for Cisco IOS XE Release 2 and includes the following sections:

•Software Packaging on the Cisco ASR 1000 Series Routers

•Cisco IOS XE Software Package Compatibility for ISSU

•Cisco IOS XE Release Compatibility Tables

•RP Memory Recommendations

•Hardware Supported

•ROMmon Version Requirements

•Determining the Software Version

•Upgrading to a New Software Release

•Cisco IOS XE to Cisco IOS Version Number Mapping

Software Packaging on the Cisco ASR 1000 Series Routers

The Cisco ASR 1000 Series Routers run Cisco IOS XE Software and use a new software packaging model consisting of:

•Consolidated packages

•Individual software sub-packages within a consolidated package

•Optional software sub-packages outside of consolidated packages

Each Cisco IOS XE consolidated package contains a collection of individual software sub-packages. Each individual software sub-package is an individual software file that controls a different element or elements of the Cisco ASR 1000 Series Router. Some individual sub-packages may be installed per element (for example, per SPA).

Note The sub-package functionality is intended for both upgrade and field support, and not all combinations of sub-packages are supported.

Each individual software sub-package can be upgraded individually, or all individual software sub-packages for a specific Cisco IOS XE consolidated package can be upgraded as part of a complete Cisco IOS XE consolidated package upgrade.

Importantly, IOS (the RPIOS individual software sub-package) is considered one of the individual software sub-packages that makes up the complete Cisco IOS XE consolidated package.

The following are the individual software sub-packages within a consolidated package:

•Route Processor

–RPBase: Provides the Route-Processor operating system.

–RPControl: Provides the control-plane processes that interface between Cisco IOS Software and the rest of the platform.

–RPIOS: Provides the Cisco IOS Software kernel, which is where Cisco IOS Software features are stored and run; each consolidated image variant has a different RPIOS sub-package: RPIOS-ipbase, RPIOS-ipbasek9, RPIOS-advipservices, RPIOS-advipservicesk9, RPIOS-adventservices, and RPIOS-adventservicesk9.

Note The RPIOS-advipservices and RPIOS-adventservices sub-packages are only available beginning with Cisco IOS XE Release 2.2.1 and later releases. These two sub-packages are not available with Cisco IOS XE Release 2.1.2 and earlier releases.

–RPAccess: Provides components to manage enhanced router access functionality.

•ESP

–ESPBase: Provides the ESP operating system and control processes, and the Cisco QuantumFlow Processor client, driver, and ucode.

•SIP

–SIPBase: Provides the SIP operating system and control processes

–SIPSPA: Provides the SPA drivers and associated field-programmable device (FPD) image (SPA FPGA image)

A Cisco IOS XE consolidated package allows users to upgrade all individual software sub-packages on the router with a single Cisco IOS XE image download. The Cisco IOS XE consolidated packages available vary based on the Route Processor (RP1 or RP2) installed in the system and the Cisco IOS XE Release.

The following are the RP1 consolidated packages:

•Cisco ASR 1000 Series RP1 IP BASE W/O CRYPTO

•Cisco ASR 1000 Series RP1 IP BASE

•Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES

•Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES W/O CRYPTO

•Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES

•Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO

Note The Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES W/O CRYPTO consolidated package is only available with Cisco IOS XE Release 2.2.1 through Cisco IOS XE Release 2.3.x. This consolidated package is not available with any other Cisco IOS XE Releases.

The Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO consolidated package is only available beginning with Cisco IOS XE Release 2.2.1 and later releases. This consolidated package is not available with Cisco IOS XE Release 2.1.2 and earlier releases.

The following are the RP2 consolidated packages:

•Cisco ASR 1000 Series RP2 IP BASE W/O CRYPTO

•Cisco ASR 1000 Series RP2 IP BASE

•Cisco ASR 1000 Series RP2 ADVANCED IP SERVICES

•Cisco ASR 1000 Series RP2 ADVANCED IP SERVICES W/O CRYPTO

•Cisco ASR 1000 Series RP2 ADVANCED ENTERPRISE SERVICES

•Cisco ASR 1000 Series RP2 ADVANCED ENTERPRISE SERVICES W/O CRYPTO

Note The RP2 consolidated packages are only available beginning with Cisco IOS XE Release 2.3.0 and later releases. The RP2 consolidated packages are not available with Cisco IOS XE Release 2.2.3 and earlier releases.

The Cisco ASR 1000 Series RP2 ADVANCED IP SERVICES W/O CRYPTO consolidated package is only available with Cisco IOS XE Release 2.3.0 through Cisco IOS XE Release 2.3.x. This consolidated package is not available with any other Cisco IOS XE Releases.

The individual software sub-packages within the consolidated packages cannot be downloaded from Cisco.com; only the Cisco IOS XE consolidated packages and optional sub-packages can be downloaded from Cisco.com. Users who want to run the router using individual software sub-packages must first download the consolidated package from Cisco.com and extract the individual software sub-packages from the consolidated package.

In addition to the individual software sub-packages within a consolidated package, optional software sub-packages that are not part of a consolidated package are available. Optional software sub-packages are downloaded separately from Cisco.com and their installation is similar to the installation of an individual software sub-package using a provisioning file. The optional sub-package must be located in the same directory with the provisioning file and the other individual sub-package files. The optional software sub-packages available vary based on the Route Processor (RP) installed in the system: RP1 or RP2:

•For the RP1, the optional software sub-package available is the Cisco ASR 1000 Series RP1 WebEx Node (asr1000rp1-sipspawmak9.version.pkg)

•For the RP2, the optional software sub-package available is the Cisco ASR 1000 Series RP2 WebEx Node (asr1000rp2-sipspawmak9.version.pkg)

Note The Cisco ASR 1000 Series RP1 WebEx Node and Cisco ASR 1000 Series RP2 WebEx Node optional software sub-packages are only available beginning with Cisco IOS XE Release 2.4.0 and later releases and are only supported in conjunction with a related RP-based Cisco ASR 1000 Series RPx IP BASE, Cisco ASR 1000 Series RPx ADVANCED IP SERVICES, or Cisco ASR 1000 Series RPx ADVANCED ENTERPRISE SERVICES consolidated package. These optional software sub-packages are not supported with earlier Cisco IOS XE releases or with any of the non-CRYPTO consolidated packages.

Note ISSU operation on the Cisco ASR 1002 and Cisco ASR 1004 systems requires the system to be operating in sub-package mode.

Note USB (or any other removable media) cannot be used to boot the system into sub-package mode.

For further information on the advantages and disadvantages of running individual sub-packages or a complete Cisco IOS XE consolidated package, and the process of extracting the individual sub-packages, see the following document:

http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/asrswcfg.html

Cisco IOS XE Software Package Compatibility for ISSU

When upgrading the Cisco IOS XE operating system software using the In Service Software Upgrade (ISSU) process, it is important to determine the compatibility of the upgraded software to your current software and hardware. The ISSU process allows software to be updated or otherwise modified while packet forwarding continues with minimal interruption.

Cisco IOS XE release compatibility using the ISSU process utilizes the SSO functionality to preserve state while software versions on the router differ, as during an upgrade. Most SSO-capable features in each Cisco IOS XE release are ISSU capable. ISSU is only supported if SSO is enabled in the configuration and the system is in a steady state (SSO ready state has been achieved). ISSU compatibility depends on the set of specific feature clients that are in use and whether they support ISSU. All ISSU upgrades include at least one IOS switchover operation. It is important to understand which features are in use and whether these features are ISSU compatible.

The Cisco ASR1006 Series Router is a hardware-redundant chassis. The hardware-redundant chassis has two ESP linecards and two RPs which exchange state using hardware links. The Cisco ASR1002 and ASR1004 Series Routers are not hardware redundant, but are software-redundancy capable. The non-redundant chassis has a single RP and a single ESP, but allows the operation of up to two IOS processes on the single RP to exchange states locally.

•Non-hardware-redundant chassis models (such as the Cisco ASR 1002 Router and Cisco ASR 1004 Router)—Supports ISSU only if the router is running in subpackage mode.

•Hardware-redundant chassis models (such as the Cisco ASR 1006 Router)—Supports ISSU when the router is running in sub-package mode or in consolidated package mode.

For a complete discussion about the ISSU upgrade process on the Cisco ASR 1000 Series Routers, including prerequisites and restrictions, see the "In Service Software Upgrade (ISSU)" chapter of the Cisco ASR 1000 Series Aggregation Services Software Configuration Guide.

Compatibility Support Policy

Rebuilds of a specific Cisco IOS XE release are intended to be fully ISSU and SSO capable for supported features between any two image pairings, however compatibility is not guaranteed for all releases. It is expected that rebuilds between release versions are compatible within a reasonable time frame.

Support for Cisco IOS XE Rebuilds

The support policy for version rebuilds is as follows:

•The immediate prior rebuild for the version is expected to be SSO and ISSU compatible with a new released rebuild of that version.

•A newly released rebuild is expected to be SSO and ISSU compatible with the current rebuild for the previous two versions.

As an example, a rebuild Y of version X is version XY. For rebuilds on the two previous versions of X, X-1 and X-2, it is expected that XY will be compatible with those versions.

Support for Special Cisco IOS XE Releases

Certain special Cisco IOS XE software releases may be made from time to time. These releases are not specified in this document and any supported SSO or ISSU interoperability must be determined on a case by case basis.

Cisco IOS XE Release Compatibility Tables

The ISSU compatibility tables in this section provide information about release pairs that are compatible and those that are not compatible for Cisco ASR1000 Series Routers. You can use this information to determine the impact of a Route Processor (RP) or Embedded Service Processor (ESP) switchover when the router is running a mixed combination of software as occurs during the whole-node ISSU procedures.

Non-SSO-capable features and non-ISSU-capable features are not included in the ISSU compatibility tables since these features lose state on any Cisco IOS XE switchover—RP switchover in the case of hardware-redundant chassis and software switchover on software-redundant chassis.

Discussion of Table Fields

In the ISSU compatibility tables, the following information is provided:

•SSO

A Cisco IOS XE release stating :SSO" for all supported SSO-capable features is fully compatible for upgrades using ISSU, even if some of the SSO-capable features are not ISSU capable. Two different versions of the software are denoted as supporting SSO if they are able to reach an SSO state when run simultaneously, regardless of the impact on specific features.

•SSO Tested

A Cisco IOS XE release stating "SSO Tested" indicates that the two releases are fully tested and supported as interoperable and will retain state across a switchover. ISSU upgrades between the releases are supported.

•SSO via <release>

A Cisco IOS XE release stating "SSO via <release>" indicates that the two releases are not interoperable and must not be run simultaneously (must not be run at the same time on the two RPs of a hardware redundant chassis and must not be co-installed as subpackages on any chassis). However, an SSO path exists using the intermediate release that is specified.

•Limited

A Cisco IOS XE release stating "Limited" indicates that the two releases have interoperability limitations. On the Cisco ASR1002 and Cisco ASR1004 routers. ISSU upgrade and downgrade are not supported. Instead you can perform a sub-package software upgrade. This process requires a RP reload.

The tables in the following sections list the compatibility of Cisco IOS XE software releases:

•ISSU Compatibility for Cisco IOS XE 2.1-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.2-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.3-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.4-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.5-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.6-Based Releases

Note The ISSU compatibility tables use the following conventions:

•The software version numbers are given first as the Cisco IOS XE release version number followed by the bundled Cisco IOS release number.

•For descriptions of the table fields, see the "Discussion of Table Fields" section.

Caution

For upgrading deployed releases prior to Cisco IOS XE 2.1.2, refer to the appropriate configuration guide. Some adjustments to the configuration procedure may be necessary due to changes in the installation command syntax. See Cisco IOS XE Software Configuration Guides .

ISSU Compatibility for Cisco IOS XE 2.1-Based Releases

Note When not labeled, the compatibility information shown in Table 1-1 applies to all platforms based on the package mode supported for ISSU on that platform. In some cases, compatibility information varies by platform and is indicated in the table.

Note Cisco ASR1002 and Cisco ASR1004 routers do not support ISSU upgrade and downgrade due to lack of hardware redundancy and the requirement to reboot the RP. However, the sub-package software upgrade and downgrade is supported only if the router is running in sub-package mode in order to minimize interruption to service.

¹For Cisco ASR 1006 Router, some ESP-maintained session state may be lost when ESPs of different versions interoperate. This affects primarily stateful firewall and network address translation functions implemented by the ESPs.

²For Cisco ASR 1006 Router, downgrade may fail depending on the features that are configured.

³For Cisco ASR 1002 Router and Cisco ASR 1004 Routers, the Cisco IOS XE software on the standby RP may spontaneously restart creating a core dump file when issu loadversion (issu command set) or request platform software package install (request platform command set) is used to simultaneously install the RP packages other than the base package (as specified by the {rpcontrol,rpaccess,rpios} portion of the filename specification). The Cisco IOS XE software on the standby RP will recover after this event.

¹For the Cisco ASR 1006 Router, some ESP-maintained session state may be lost when ESPs of different versions interoperate. This affects primarily stateful firewall and network address translation functions implemented by the ESPs.

²For the Cisco ASR 1006 Router, use of new features in the uprev release may be limited after ISSU. To correct this issue, perform an additional redundancy force-switchover after completing all steps of the ISSU procedure and after the device has reached SSO. Alternatively, a chassis reload also addresses the issue.

³For the Cisco ASR 1002 Router and Cisco ASR 1004 Routers, when ISSU is used to upgrade router software, new features available in the new version are configurable as soon as the RP software portion of the update has been completed for both active and standby IOS. New features will be fully reflected in the operation of the router once the linecard images are also updated. Under some circumstances, the new features may not be available until after the final step of the Cisco ASR1002 and Cisco ASR1004 ISSU procedure is performed (chassis reload).

⁴For the Cisco ASR 1002 Router and Cisco ASR 1004 Routers, the Cisco IOS XE software on the standby RP may spontaneously restart creating a core dump file when issu loadversion (issu command set) or request platform software package install (request platform command set) is used to simultaneously install the RP packages other than the base package (as specified by the {rpcontrol,rpaccess,rpios} portion of the filename specification). The Cisco IOS XE software on the standby RP will recover after this event.

⁵For the Cisco ASR 1006 Router, downgrade may fail depending on the features that are configured.

⁶After ISSU procedure, you might need to run an additional switchover to ensure R0 is active.

⁷The forwarding processor (FP) remains in "init" state during ISSU sub-package procedure when broadband QoS is configured. The workaround is to recreate some broadband sessions, tear down all sessions, or unconfigure QoS queueing feature on the broadband sessions and then reload the FP. For more information, refer to CSCsz09462 in the Bug Toolkit.

ISSU Compatibility for Cisco IOS XE 2.3-Based Releases

Note When not labeled, the compatibility information shown in Table 1-3 applies to all platforms based on the package mode supported for ISSU on that platform. In some cases, compatibility information varies by platform and is indicated in the table.

Note Cisco IOS XE 2.4.2t does not support ISSU upgrade and downgrade.

¹For the Cisco ASR 1006 Router, use of new features in the uprev release may be limited after ISSU. To correct this issue, perform an additional redundancy force-switchover after completing all steps of the ISSU procedure and after the device has reached SSO. Alternatively, a chassis reload also addresses the issue.

²A loopback interface Outbound Cache Entry (OCE) may be lost after an RP failover.

³For ATM SPAs on the Cisco ASR1000 Series Routers, ISSU from releases prior to Cisco IOS XE Release 2.5.0 to Cisco IOS XE Release 2.5.0, or from Cisco IOS XE Release 2.5.0 to a release prior to Cisco IOS XE Release 2.5.0, is not supported. If you want to perform ISSU in this environment, you must first remove the configuration from the ATM SPAs on the router, and then shut down the SPAs using the shutdown command prior to running the ISSU process.

⁴PPP sessions requiring AAA authentication and authorization will not be synchronized to standby after ISSU upgrade procedure. This applies to scenarios where the Cisco ASR 1000 Series Router is acting as a PPP Termination and Aggregation (PTA) or L2TP network server (LNS) terminating PPP sessions.

RP Memory Recommendations

The Cisco IOS XE images and packages available vary based on the Route Processor (RP) installed in the system: RP1 or RP2.

•Table 7 describes the RP1 consolidated package images, their individual software sub-package contents, and their memory recommendations.

•Table 9 describes the RP1 optional sub-package images and their memory recommendations.

•Table 9 describes the RP2 consolidated package images, their individual software sub-package contents, and their memory recommendations.

•Table 10 describes the RP2 optional sub-package images and their memory recommendations.

Each Cisco IOS XE image also contains two provisioning files: asr1000rpx-packages.image.version.conf and packages.conf. A provisioning file is used for booting only in cases where the individual modules are extracted from the Cisco IOS XE image and then used to run the router. Either provisioning file can be used.

Note No In Service Software Upgrade (ISSU) is possible between different image types.

Cisco IOS XE Release 2.5 provides an enhancement that allows you to segment VPN traffic within a DMVPN tunnel.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/sec_secure_connectivity/configuration/guide/sec_DMVPN_xe.html

AAA - Improvements for Broadband IPv6

This feature is supported in Cisco IOS XE Release 2.5.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/ipv6/configuration/guide/ip6-adsl_dial_xe.html

ANCP - ATM Support

You can enable ANCP support on an ATM interface by using the enable ancp command. This is one of the optional steps for configuring PVC.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/atm/configuration/guide/atm_cfg_atm_xe.html

ATM F4 Ping

The F4 Operations, Administration, and Maintenance (OAM) Ping without Virtual Path (VP) Creation feature enables you to determine problems at the virtual path (VP) level using the ping command. Using

this feature, you can create and remove virtual circuit identifiers (VCIs) that correspond to the VP segment and the VP end, in the absence of VP configuration. After creating the VCIs you can use the ping atm command to isolate connection problems.

ATM Sub-interface Multipoint

ATM supports two types of interfaces: point-to-point and multipoint.

–Point-to-point subinterface—With point-to-point subinterfaces, each pair of routers has its own subnet. If you put the PVC on a point-to-point subinterface, the router assumes that there is only one point-to-point PVC configured on the subinterface. Therefore, any IP packets with a destination IP address in the same subnet are forwarded on this virtual circuit (VC). This is the simplest way to configure the mapping and is therefore the recommended method.

–- Multipoint networks—Multipoint networks have three or more routers in the same subnet. If you put the PVC in a point-to-multipoint subinterface or in the main interface (which is multipoint by default), you need to either configure a static mapping or enable inverse Address Resolution Protocol (ARP) for dynamic mapping.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/atm/configuration/guide/atm_cfg_atm_xe.html

ATM VC Ingress Policing

This feature module describes how to configure QoS hierarchical queueing policy maps on sessions and ATM VCs in ATM Digital Subscriber Line Access Multiplexer (A-DSLAM) applications.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/qos/configuration/guide/ppp_ses_que_atm_vc_xe.html

BGP Best External

The BGP Best External feature provides the capability of configuring the additional backup paths and advertises the best-external route which is the most preferred route among the routes received by a router from its eBGP peers. The best-external route can be used in case the primary PE fails or the primary PE link fails thereby reducing traffic loss and aiding in achieving faster PIC time.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/iproute_bgp/configuration/guide/irg_best_external_xe.html

BGP Multicast Inter-AS (IAS) VPN

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/iproute_bgp/configuration/guide/irg_best_external_xe.html

BGP PIC Edge for IP/MPLS

The BGP PIC feature provides the ability to converge BGP routes within sub-seconds instead of multiple seconds and allows you to configure your BGP to minimize traffic loss and improve convergence when a link between the PE and CE router fails.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/iproute_bgp/configuration/guide/irg_best_external_xe.html

BGP VPLS Auto Discovery Support on Route Reflector

On the ASR1000, BGP Route Reflector was enhanced to be able to reflect BGP VPLS prefixes without having VPLS explicitly configured on the route reflector. The route reflector reflects the VPLS prefixes to other provider edge (PE) routers so that the PEs do not need to have a full mesh of BGP sessions.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/iproute_bgp/configuration/guide/irg_int_features_xe.html

Configurable Domain Name Prefix and Suffix Stripping

New Software Features in Cisco IOS XE Release 2.4.1

This section lists new and changed features in Cisco IOS XE Release 2.4.1. Some features may have been released in earlier Cisco IOS software releases and have been changed in Cisco IOS XE Release 2.4.1.

•IPv6 IPSec Static Virtual Interface

•IPSec QoS Group-Based LLQ QoS

•ALG Support for SIP T.38 Fax Relay over IP

•ISIS Support for IPv6

IPv6 IPSec Static Virtual Interface

Static Virtual Tunnel Interface (SVTI) configurations can be used for site-to-site connectivity in which a tunnel provides always-on access between two sites. The advantage of using SVTIs as opposed to map configurations is that users can enable dynamic routing protocols on the tunnel interface without the extra 24 bytes required for GRE headers, thus reducing the bandwidth for sending encrypted data.

For more information on SVTIs, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/ipv6/configuration/guide/ip6-ipsec_xe.html

IPSec QoS Group-Based LLQ QoS

A limitation exists when IPSec and QoS are configured on an interface. IPSec uses the egress QoS policy to determine if a packet is a high priority packet before it enqueues it in a low latency queue (LLQ) of the crypto processor. For tunnel interfaces when the QoS policy is applied to the egress physical interface, Tunnel Protection is applied on the tunnel interface, and IPSec cannot determine if the packet is a high priority packet. In this scenario, high priority packets are queued to the default queue—increasing latency and traffic loss during oversubscription.

Starting with Cisco IOS XE Release 2.4.1, QoS group-based LLQ for IPSec provides LLQ functionality before crypto for the limitation described earlier. The idea is to use QoS groups to identify high priority traffic in the IPSec module. Packets are marked with a QoS group at the ingress interface. The user designates certain QoS groups to be used as high priority before crypto.

A new IOS XE command allows the user to configure certain QoS groups as high priority for IPSec:

[no] platform ipsec llq qos-group group_num

This command specifies that packets with QoS group group_num (allowed range 1 to 99) are to be treated as high priority packets before crypto and, therefore, are queued into a LLQ before reaching the crypto processor.

ALG Support for SIP T.38 Fax Relay over IP

The SIP Application Layer Gateway has been enhanced to provide NAT and Firewall ALG support for T.38 Fax Relay over IP.

ISIS Support for IPv6

Intermediate System (IS-IS) has been enhanced to provide Internet Protocol version 6 (IPv6).

New Hardware Features in Cisco IOS XE Release 2.4.0

The following new hardware features are supported by the Cisco ASR 1000 Series Routers for Cisco IOS XE Release 2.4.0:

Cisco ASR 1002-Fixed Router

The Cisco ASR 1002-Fixed (Cisco ASR 1002-F) Router is the smallest of the Cisco ASR 1000 Series Aggregation Services Routers and supports all the general-purpose routing and security features of the Cisco ASR 1002 Router.

The Cisco ASR 1002-F Router uses the same internal control and data-plane architecture as the Cisco ASR 1002 router with the following variations:

•Has all integrated components: an integrated route processor (Cisco ASR1000-RP1), an integrated embedded services processor (2.5-Gbps Cisco ASR 1000 Series ESP), and an integrated 4xGE SPA interface (Cisco ASR1000-SIP10)

•Supports 2.5 GB of system bandwidth

•Is supported only with Cisco IOS XE Release 2.4.0 and later releases

For information about the Cisco ASR 1002-F Router, see the following documents:

Cisco ASR 1000 Series Aggregation Services Routers Hardware Installation Guide at the following location:

http://www.cisco.com/en/US/docs/routers/asr1000/quick/start/guide/asr1_qs2F.html

New Shared Port Adapters

Cisco IOS XE Release 2.4.0 introduces support for the following new shared port adapters (SPAs):

POS SPAs

•8-Port OC-3 POS SPA (SPA-8XOC3-POS)

•2-Port, 4-Port, and 8-Port OC-12 POS SPAs (SPA-2XOC12-POS, SPA-4XOC12-POS, and SPA-8X0C-12-POS)

•1-Port OC-48 POS SPA (SPA-1XOC48POS/RPR)

•1-Port OC-192 POS SPA (SPA-OC192POS-XFP)

Services SPA

•Cisco WebEx Node for ASR 1000 Series (SPA-WMA-K9)

The Cisco WebEx Node for ASR 1000 Series is a full-height SPA designed to run an application which is part of the WebEx MediaTone network management application. The Cisco WebEx Node for ASR 1000 Series improves the functionality of WebEx meeting services by adding the meeting servers into the SPA itself. This technology provides the following advantages:

–Improves performance for users inside the company firewall.

–Reduces the bandwidth going out of company firewall (to the WebEx MediaTone network).

–Provides better security by reducing traffic outside the company.

By moving the switching components of the WebEx Collaboration Cloud into the Cisco WebEx Node for ASR 1000 Series, the WebEx clients in the enterprise network need only connect to the Cisco WebEx Node for ASR 1000 Series. This reduces the traffic between the enterprise network and the WebEx MediaTone network, greatly reducing the customer's Internet bandwidth requirements.

Each Cisco WebEx Node for ASR 1000 Series can be configured to perform either web conferencing or voice and video conferencing, but not both features at the same time. Each Cisco WebEx Node for ASR 1000 Series uses the same software package that includes both features; the conferencing feature that actually runs on each SPA is determined by the WebEx Service Plan the customer has purchased. The WebEx MediaTone network retains the Cisco WebEx Node for ASR 1000 Series configuration files that the SPA retrieves each time the SPA boots. Multiple Cisco WebEx Nodes for ASR 1000 Series can be installed on the same Cisco ASR 1000 Series Router chassis to increase the conferencing performance or to provide conferencing coverage for both web and voice and video sessions.

Etherchannel Flow Based Limited 1:1 Redundancy

The EtherChannel Flow-Based Limited 1:1 Redundancy feature provides a way to configure load balancing at the port-channel level based on different flows of traffic. You can identify different flows of traffic based on key fields in the data packet and balance the traffic load according to those traffic flows. To use EtherChannel flow-based limited 1:1 redundancy, you configure an EtherChannel with two ports (one active and one standby). If the active link goes down, the EtherChannel stays up and the system performs fast switchover to the hot-standby link. When the failed link becomes operational again, the EtherChannel performs another fast switchover to revert to the original active link.

PKI—CLI to Control Certificate Revocation List (CRL) Cache

The PKI-CLI to Control Certificate Revocation List (CRL) Cache feature allows the administrator to control the CRL cache size. CRLs are received by Cisco IOS software in Distinguished Encoding Rules (DER) encoded format. Because processing a DER encoded CRL uses CPU memory, Cisco IOS software allows CRLs either to be stored in cache after being processed or to be decoded. Configuring the CRL cache size allows the amount of memory to be decreased (for example, if low memory conditions exist) or to be increased (for example, when a large number of CRLs are being processed), resulting in better performance.

The following commands were introduced or modified by this feature: crypto pki crl cache and show crypto pki crls. The crypto pki crl cache command allows the administrator to set the maximum amount of volatile memory used to cache CRLs. When the crypto pki crl cache command is configured, the show crypto pki crls command output includes information on the CRL cache size.

New Cisco ASR 1000 Embedded Services Processors

Cisco IOS XE Release 2.2.1 introduces support for the following new Embedded Services Processors (ESPs):

Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable

The Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable (Cisco ASR1000-ESP10-N) is a non-crypto capable version of the encryption-enabled 10-Gbps Cisco ASR 1000 Series ESP (Cisco ASR1000-ESP10).

The Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable provides a Cisco ASR 1000 solution for customers who are under export restrictions and not qualified to implement products that support strong encryption services. The Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable feature support is the same as the 10-Gbps Cisco ASR 1000 Series ESP except that IPSec and other data-plane cryptographic features are not supported.

The Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable is supported on all Cisco ASR 1000 Series chassis but should only be used with following consolidated packages that do not contain cryptographic (K9) software:

•Cisco ASR 1000 Series RP1 IP BASE W/O CRYPTO

•Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES W/O CRYPTO

•Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO

Note The Cisco ASR 1000 Series RP1 IP BASE W/O CRYPTO, Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES W/O CRYPTO, and Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO consolidated packages do not require export qualification and can also run on the encryption-enabled 10-Gbps Cisco ASR 1000 Series ESP. The K9-based consolidated packages (Cisco ASR 1000 Series RP1 IP BASE, Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES and Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES) will never be supported on the Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable hardware.

Note The Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable should never be inserted into a chassis using K9 software or the router may reload.

Note The Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable and 10-Gbps Cisco ASR 1000 Series ESP should not be mixed in a hardware-redundant chassis.

For information about the Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable, see the following documents:

http://www.cisco.com/en/US/docs/ios/ipmulti/configuration/guide/imc_basic_cfg.html

Cisco Firewall and WAAS Inter-Op

The Cisco Firewall and WAAS Interoperability feature enables a router configured with a firewall to successfully communicate with a cache engine, such as a Wide Area Application Acceleration (WAAS) device that is using the Web Cache Communication Protocol (WCCP).

WAAS optimizes remote access to applications.When the cache engine is a WAAS device, it can optimize TCP flow by modifying TCP headers. During the TCP three-way handshake, the WAAS device can add an extra TCP option in the header to indicate that the flow will be optimized. When the TCP session is established, the WAAS device can modify the sequence and acknowledge number in the TCP header to optimize the data flow.

When a Cisco firewall is configured on the router, the packets have to be inspected by the firewall. Depending on the deployment scenario, the firewall inspects packets as follows:

•For client-to-server packets, the firewall inspects packets in the redirect path and ignores packets in the return path.

•For server-to-client packets, the firewall inspects packets in the return path and ignores packets in the redirect path.

•If the firewall encounters a TCP SYN packet with the 0x21 option, the firewall knows that this packet is already a WAAS flow. The firewall will adjust the Layer 4 state to reflect the 2-GB jump in sequence and acknowledge numbers. No Layer 7 inspection will be applied to the flow.

•Although the firewall will ignore the same packets in either the redirect or the return path, the firewall must still perform a session lookup to get the information about the direction of the packet (from client to server or server to client).

This feature has the following restrictions:

•Only Generic Routing Encapsulation (GRE) redirect and return is supported. Layer 2 redirect and return is not supported.

•Certain platforms, such as the Cisco 2800 series, support an inbox network service module (WAAS-NM) that provides WAAS services. The Cisco ASR 1000 series routers do not support inbox network service modules; thus, the router will not support WAAS-NM.

Class-Based Marking

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/mrkg_netwk_traffic.html

Class Based Weighted Fair Queuing (CBWFQ)

CBWFQ extends the standard weighted fair queueing (WFQ) functionality to provide support for user-defined traffic classes. For CBWFQ, you define traffic classes based on match criteria such as protocols, access control lists (ACLs), and input interfaces.

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/config_wfq.html

Control Plane Policing (CoPP)

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/ctrl_plane_policng.html

Integrated Session Border Controller

Cisco IOS XE Release 2.2.1 introduces support for the following new Integrated Session Border Controller (SBC) features:

•Full Support for Wildcard Response

•H.248 Protocol—Acknowledgment Support for Three-Way Handshake

•H.248 ServiceChange Handoff

•Improved Media Timeout Detection

•Interim Authentication Header Full Support

•IPSec Pinhole Support—Twice NAT for IPv4 and No NAT for IPv6

Full Support for Wildcard Response

Previously Session Border Controller (SBC) supported H.248 wildcard operations that were restricted to W-Modify or W-Subtract requests, which yielded summary wildcard responses. This feature introduces support for a complete wildcard response. A wildcard H.248 Subtract or Modify operation now returns a complete response with per-termination statistics.

H.248 Protocol—Acknowledgment Support for Three-Way Handshake

The data border element (DBE) supports a three-way handshake for H.248 messages. The DBE supports sending of an acknowledgement for a three-way handshake after receiving the transaction response from the media gateway controller (MGC), as described in Annex D.1.2 and Annex D.1.2.2 of H.248.1 v3 Gateway Control Protocol.

H.248 ServiceChange Handoff

The ServiceChange Handoff functionality on Integrated Session Border Controller conforms to section 7.2.8, ServiceChange, and section 7.2.8.1.1, ServiceChangeMethod, of the H.248.1 v3 Gateway Control Protocol. The ServiceChange Handoff functionality allows a media gateway controller (MGC) to hand over control of a media gateway (MG) to another MGC. The MGC sends a ServiceChange message to the MG that it is currently associated with to request that the MG terminate that association and the MG form a new association with an MGC identified in the ServiceChange message.

Improved Media Timeout Detection

In the previous media timeout functionality on the data border element (DBE), if no SBC packets have been seen by the configured number of seconds since the call has been established, then the DBE generates a media timeout alert to the SBE. The Improved Media Timeout Detection feature delays reporting of the media timeout event by instructing the DBE to wait until it has received the first packet since the call has been established. Only then does the media timeout timer start counting the number of seconds for which it has not seen an SBC packet. At the end of the count, the DBE generates an alert to the SBE.

Interim Authentication Header Full Support

Integrated SBC offers full support of Interim Authentication Header (IAH) that conforms to section 10.2, Interim AH Scheme, of the H.248.1 v3 Gateway Control Protocol. An IAH is part of every H.248 message generated by the data border element (DBE) to the media gateway controller (MGC). Information in the IAH is used to authenticate and check the integrity of packets, thus ensuring packet security. The DBE generates an IAH for outgoing H.248 messages and can verify the Authentication Header for incoming H.248 messages. The IAH scheme inserts the IAH within the H.248.1 protocol header.

IPSec Pinhole Support—Twice NAT for IPv4 and No NAT for IPv6

The IPSec Pinhole Support—Twice NAT for IPv4 and No NAT for IPv6 feature adds support for voice calls over IPSec tunnels and adds support for IPSec address-only pinholes. This support enables the DBE to forward IPSec packets when the port cannot be determined because the port is within the encrypted portion of the frame. Thus, IPSec support handles the IPSec requirement that does not allow use of port numbers for session lookup or translation. Currently single IPSec pinholes are supported, whereby both IKE and the encrypted IPSec traffic passes through the same pinhole.

For information about these SBC features, see the following document:

http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/sbc/2_xe/sbc_2_xe_book.html

L2TP AAA Accounting Include NAS-PORT (VPI/VCI)

The L2TP AAA Accounting Include NAS-PORT (VPI/VCI) feature allows an L2TP Network Server (LNS) to send the NAS Port-ID (attribute 5), as part of the accounting record to the RADIUS authentication, authorization, and accounting (AAA) server.

Limitations and Restrictions

In Cisco IOS XE Release 2.2.1, the L2TP AAA Accounting Include NAS-PORT feature does not support the asynchronous transfer mode (ATM) virtual path identifier/virtual channel identifier (VPI/VCI) pair.

L2TP HA Session SSO/ISSU on LAC/LNS

The L2TP HA Session SSO/ISSU on a LAC/LNS feature provides a generic Stateful Switchover/In Service Software Upgrade (SSO/ISSU) mechanism for Layer 2 Tunneling Protocol (L2TP) on a Layer 2 Access Concentrator (LAC) and a Layer 2 Network Server (LNS). This feature preserves all fully-established Point-to-Point Protocol (PPP) and L2TP sessions (including Multihop) during an SSO switchover, or an ISSU upgrade or downgrade.

L3 MPLS VPN Over GRE

L3 MPLS VPN over GRE provides a mechanism for tunneling Multi Protocol Label Switching (MPLS) packets over a non-MPLS network.

The L3 MPLS VPN over GRE feature utilizes MPLS over Generic Routing Encapsulation (MPLSoGRE) to encapsulate MPLS packets inside IP tunnels; thus creating a virtual point-to-point link across non-MPLS networks. This allows users of primarily MPLS networks to continue to use existing non-MPLS legacy networks until migration to MPLS is possible.

Per Subscriber Firewall on LNS

The Per-Subscriber Firewall on LNS feature enables the zone-based policy firewall configuration model to be implemented on the Cisco ASR 1000 Series Router. Zone-based policy firewall is a unidirectional firewall policy between groups of interfaces known as zones. (Previously, Cisco firewalls were configured as an inspect rule only on interfaces. Traffic entering or leaving the configured interface was inspected based on the direction that the inspect rule was applied.) Now, interfaces are assigned to zones, and inspection policies are applied to traffic moving between the zones. Interzone policies offer considerable flexibility and granularity, so different inspection policies can be applied to multiple host groups connected to the same router interface.

In addition to the zone-based policy firewall model, the Per-Subscriber Firewall on LNS feature introduces the following additional functionality for the Cisco ASR 1000 Series Router:

•Dynamic zone assignment for virtual access interfaces

Subscribers can be assigned to a zone in one of two ways:

–Using the configuration on the virtual-template interface, which can be useful when placing subscribers in a default zone.

–Using the RADIUS vendor-specific attribute (VSA), which enables zone assignment to be determined when the session is authorized.

•PPP session-level granularity for zone-based policy firewall

Stateful inspection and application monitoring occur at the PPP session, enabling the full suite of firewall and broadband features to be applied per subscriber, simultaneously. That is, extra routers or service blades are not required to support the firewall functionality. The firewall functionality is applied by the packet processor engine (PPE) in the forwarding path for broadband traffic.

•Per-subscriber drop log messages

Service providers can track drops on a per-subscriber basis by including the subscriber's username in the drop log messages. These drop log messages can also be sent to an off-box server for additional processing.

•Zone pairs with matching source and destination zones

Service providers can customize the firewall policy for traffic between subscribers in the same zone. Customization is useful for overriding the default behavior, which is the passage of all traffic within the same zone.

For more information on zone-based policy firewalls, see the following documents:

BFD IPv6 Encaps Support

The Bidirectional Forwarding Detection for IPv6 (BFDv6) protocol provides fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols. In addition to fast forwarding path failure detection, BFD provides a consistent failure detection method for network administrators. The BFD IPv6 Encaps Support feature updates the Bidirectional Forwarding Protocol (BFD) protocol to provide IPv6 support and accommodate IPv6 addresses.

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-bfd.html

BFD—IPv6 Static Route Support

The BFD—IPv6 Static Route Support feature enables BFD for IPv6 to be used to verify next-hop reachability for IPv6 static routes.

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-bfd.html

DHCP—DHCPv6 Relay Agent Notification for Prefix Delegation

The DHCP—DHCPv6 Relay Agent Notification for Prefix Delegation feature allows the router working as a DHCPv6 relay agent to find prefix delegation options by reviewing the contents of a DHCPv6 packet that is being relayed by the relay agent to the client.

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-dhcp.html

DHCP Relay Server ID Override and Link Selection Option 82 Suboptions

The DHCP Relay Server ID Override and Link Selection Option 82 Suboptions feature enables the relay agent to be part of all DHCP message exchanges by supporting the use of two suboptions of the relay agent information option (option 82). This design allows DHCPv4 to operate in networks where direct communication between the client and server is not possible or desired. When used together, these two suboptions enable the deployment of an architecture where it is desirable to have all DHCP traffic flow through the relay agent, allowing for greater control of DHCP communications.

This feature also introduces the capability to manually configure the interface for the relay agent to use as the source IP address for messages relayed to the DHCP server. This configuration allows the network administrator to specify a stable, hardware-independent IP address (such as a loopback interface).

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/ipaddr/configuration/guide/iad_dhcpservidlink_mcp.html

DHCPv6 Ethernet Remote ID Option

The DHCPv6 Ethernet Remote ID Option feature adds the remote-ID option to relayed (RELAY-FORWARD) DHCPv6 packets.

For information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-dhcp.html

Integrated Session Border Controller

The Integrated Session Border Controller (SBC) is introduced on the Cisco ASR 1000 Series Routers. The Integrated SBC is integrated with other features on the Cisco ASR 1000 Series Routers, without requiring additional application-specific hardware, such as service blades, or the need to create an overlay network of standalone SBC appliances.

Session border controllers are used as key components in interconnecting Voice over IP (VoIP) and multimedia networks of different enterprise customers and service providers. SBCs are deployed at the edge of networks to meet the need for secure, intelligent border element functions. Using SBCs, the end user can make voice and video calls to another end user without being concerned about protocols, network reachability, or safety of the network.

The SBC enables direct IP-to-IP interconnect between multiple administrative domains for session-based services providing protocol and signaling interworking, security, Quality of Service (QoS), network hiding, statistics gathering, and admission control and management.

Currently the data border element (DBE) functionality of the Integrated Session Border Controller is supported on the Cisco ASR 1000 Series Routers.

MQC—Distribution of Remaining Bandwidth Using Ratio

The MQC—Distribution of Remaining Bandwidth Using Ratio feature allows service providers to configure a bandwidth-remaining ratio on subinterfaces and class queues. This ratio specifies the relative weight of a subinterface or queue with respect to other subinterfaces or queues. During congestion, the router uses this bandwidth-remaining ratio to determine the amount of excess bandwidth (unused by priority traffic) to allocate to a class of nonpriority traffic.

Quality of Service for Gigabit EtherChannels

The Quality of Service: Policies Aggregation feature allows the default traffic classes of different policy maps on the same physical interface to be configured as a single traffic class within the Modular QoS CLI. The Quality of Service for Gigabit EtherChannels feature extends the functionality introduced in the Quality of Service: Policies Aggregation feature by allowing the default traffic classes of different member links in the same Gigabit EtherChannel bundle to be configured as a single traffic class within the Modular QoS CLI.

This feature is documented as part of the Quality of Service: Policies Aggregation feature.

VLAN Mapping to GEC Member Links

The VLAN Mapping to GEC Member Links feature allows for the static assignment of user traffic as identified by a VLAN ID to a given member link of a GEC bundle. Network administrators can manually assign VLAN subinterfaces to a primary and secondary link. Load balancing to downstream equipment can be configured, regardless of the downstream equipment capabilities, and will provide failover protection by redirecting traffic to the secondary member link if the primary link fails. Member links are supported with up to 16 bundles per chassis.

Release Note Only Software Features in Cisco IOS XE Release 2.1.0

This section describes features that are supported in Cisco IOS XE Release 2.1.0 but that are documented only in the release notes and do not have a link to a feature module.

•VPN Routing Forwarding (VRF) Framed Route (Pool) Assignment via PPP

8-Way CEF Load Balancing

Destination IP prefixes are added to the routing table by routing protocols or static routes. Each path is a valid route to reach the destination prefix. The set of active paths is the set of paths with the best cost. Cisco Express Forwarding load balancing is the ability to share the traffic to a destination prefix over up to eight active paths (an increase from the previous support of six active paths). Load among the active paths can be distributed per destination.

BGP Reduction in Transient Memory Usage

The BGP Reduction in Transient Memory Usage feature implements a reduction in transient memory usage by BGP when BGP updates are built in Cisco IOS XE Release 2.

CEF Support for IP Routing Between IEEE 802.1 Q VLANs

Cisco Express Forwarding (CEF) is supported on interfaces on which IEEE 802.1Q encapsulation has been enabled at the subinterface level. You no longer have to disable CEF operation on interfaces that are using IEEE 802.1Q encapsulation on VLAN subinterfaces.

Class-Based Quality of Service Management Information Base

The Class-Based Quality of Service Management Information Base (Class-Based QoS MIB) provides read access to class-based QoS configurations. This MIB also provides QoS statistics information based on the Modular QoS CLI, including information regarding class map and policy map parameters.

This Class-Based QoS MIB is actually two MIBs: CISCO-CLASS-BASED-QOS-MIB and CISCO-CLASS-BASED-QOS-CAPABILITY-MIB.

Compression Control

The PPP Compression Control Protocol (CCP) defines a method for negotiating data compression over PPP links. These links can be either leased lines or circuit switched WAN links such as ISDN. PPP CCP allows vendors to support multiple data compression algorithms.

DLR Enhancements: PGM RFC-3208 Compliance

In compliance with RFC 3208, the DLR Enhancements: PGM RFC-3208 Compliance feature adds off-tree designated local repairer (DLR) support and redirecting poll response (POLR) capability for upstream DLRs to the Cisco implementation of Pragmatic General Multicast (PGM).

Frame Relay FRF.1.2 Annex A Support

The FRF.1.2 Annex A Support feature is also called Local Management Interface (LMI) segmentation. It supports an enhancement to the Frame Relay LMI protocol where LMI full status messages are segmented because of MTU constraints or large numbers of permanent virtual circuits (PVCs). This feature is useful when the maximum MTU size is insufficient to accommodate the large number of PVCs on the link. During Frame Relay internetworking with other Layer 2 protocols, the MTUs on each interface must match. In software without the FRF.1.2 Annex A Support feature, you cannot change the MTU size on the Frame Relay side and place all PVC data into one LMI packet. The FRF.1.2 Annex A Support feature removes this limitation.

The FRF.1.2 Annex A standard adds a new message type "Full status continued" to an LMI packet. When a DCE determines that it cannot fit all PVCs into one packet (enforced by the MTU size), the message type is set to "Full status continued." The DTE responds to "Full status continued" messages that are sent to this packet immediately instead of waiting for the T391 timer to expire. The DCE sends the remaining PVCs in one or more "Full status continued" messages until all the remaining PVCs can fit into one message. At this point, a normal "Full status" message is sent.

If the DTE receives a "Full status" or "Full status continued" STATUS message in response to a "Full status continued" STATUS ENQUIRY message, this exchange indicates a lower-valued data-link connection identifier (DLCI) than the prior "Full status continued" STATUS message (and is considered to be an error event), and PVC information elements (IEs) are not processed. The next time the T391 timer expires, the "Full status" STATUS ENQUIRY procedure is reinitiated.

This feature follows the FRF.1.2 implement agreement [1] and allows Cisco IOS software to be compliant with the FRF.1.2 standard. The implementation is platform-independent and applies to all platforms running Cisco IOS software that support Frame Relay. This feature interoperates only with existing Cisco IOS software releases where all PVCs can be reported in one packet. A router running the new functionality must be able to interoperate with routers running existing Cisco IOS software releases and with routers that support the new functionality using the continuation status request and reply frames. Only LMI types Q.933A and ANSI support the FRF.1.2 Annex A standard.

You can track "Full status continued" packets by using the debug frame-relay lmi command in privileged EXEC mode. An extra field, 04, has been added to the display output. The following example indicates where in the report to look for this field (the text is in bold for this example):

17:42:39: Serial1(out): StEnq, myseq 126, yourseen 125, DTE up

17:42:39: datagramstart = 0x40058DA4, datagramsize = 13

17:42:39: FR encap = 0x00010308

17:42:39: 00 75 51 01 04 53 02 7E 7D

The string segment "active/inactive" in the display of the show interface commands indicates whether the FRF.1.2 Annex A standard is triggered. The report indicates active when routers receive the "Full status continued" message; otherwise, the report indicates inactive.

Interfaces MIB: SNMP Context Based Access

The Interfaces MIB (IF-MIB) has been modified to support context-aware packet information in Virtual Route Forwarding (VRF) environments. VRF environments require that contexts apply to Virtual Private Networks (VPNs) so that clients can be given selective access to the information stored in the IF-MIB. Clients that belong to a particular VRF can access information about the interface from the IF-MIB that belongs to that VRF only. When a client tries to get information from an interface that is associated with a particular context, the client can see only the information that belongs to that context and cannot see IF-MIB information that is associated with interfaces that are connected to another VRF to which it is not entitled. No commands have been modified or added to support this feature.

The IF-MIB supports all tables that are defined in RFC 2863 and the CISCO-IFEXTENSION-MIB.

ISSU - IGMP Snooping

This ISSU - IGMP Snooping feature adds ISSU support for IGMP Snooping.

NAT—Performance Enhancement - Translation Table Optimization

The NAT - Performance Enhancement - Translation Table Optimization feature provides greater structure for storing translation table entries and an optimized look up in the table for associating table entries to IP connections.

Parse Bookmarks

The Parse Bookmarks feature quickly processes consecutive similar commands, such as access-lists and prefix-lists, up to five times faster. The Parse Bookmarks feature reduces boot time and load time for large configurations with many similar consecutive commands. This feature is an enhancement to the parsing algorithm; therefore no configuration changes are needed.

PPPoE Over Gigabit Ethernet Interface

The PPPoE over Gigabit Ethernet Interface feature enhances PPP over Ethernet (PPPoE) functionality by adding support for PPPoE and PPPoE over IEEE 802.1Q VLANs on Gigabit Ethernet interfaces.

RADIUS Attribute 52 and 53 Gigaword Support

The RADIUS Attribute 52 and Attribute 53 Gigaword Support feature introduces support for Attribute 52 (Acct-Input-Gigawords) and Attribute 53 (Acct-Output-Gigawords) in accordance with RFC 2869. Attribute 52 keeps track of the number of times the Acct-Input-Octets counter has rolled over the 32-bit integer throughout the course of the provided service; attribute 53 keeps track of the number of times the Acct-Output-Octets counter has rolled over the 32-bit integer throughout the delivery of service. Both attributes can be present only in Accounting-Request records where the Acct-Status-Type is set to "Stop" or "Interim-Update." These attributes can be used to keep accurate track of and bill for usage.

RADIUS Attribute 77 for DSL

The RADIUS Attribute 77 for DSL feature introduces support for attribute 77 (Connect-Info) to carry the textual name of the virtual circuit class associated with the given permanent virtual circuit (PVC). (Although attribute 77 does not carry the unspecified bit rate (UBR), the UBR can be inferred from the classname used if one UBR is set up on each class.) Attribute 77 is sent from the network access server (NAS) to the RADIUS server via Accounting-Request and Accounting-Response packets.

Selective Packet Discard (SPD)

When in severe overload conditions, routers that cannot keep up with the incoming packet stream must drop packets. If no intelligence is applied to choosing which ones to discard, this will impact the stability of routing protocols. This feature applies some simple choices to selectively discard packets likely to be unimportant for routing and interface stability. SPD is enabled by default; there are no commands or configuration tasks required.

TCP MIB for RFC4022 Support

To locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use Cisco MIB Locator found at the following URL:

http://www.cisco.com/go/mibs

VPN Routing Forwarding (VRF) Framed Route (Pool) Assignment via PPP

The VPN Routing Forwarding (VRF) Framed Route (Pool) Assignment via PPP feature introduces support to make the following RADIUS attributes VRF aware: attribute 22 (Framed-Route), a combination of attribute 8 (Framed-IP-Address) and attribute 9 (Framed-IP-Netmask), and the Cisco VSA route command. Thus, static IP routes can be applied to a particular VRF routing table rather than the global routing table.

Limitations and Restrictions

This section lists the limitations and restrictions that apply to the Cisco ASR 1000 Series Routers for Cisco IOS XE Release 2 and contains the following sections:

•Limitations and Restrictions in Cisco IOS XE Release 2.3.0

•Limitations and Restrictions in Cisco IOS XE Release 2.2.3

•Limitations and Restrictions in Cisco IOS XE Release 2.2.1

•Limitations and Restrictions in Cisco IOS XE Release 2.1.1

•Limitations and Restrictions in Cisco IOS XE Release 2.1.0

Limitations and Restrictions in Cisco IOS XE Release 2.3.0

This section describes limitations and restrictions in Cisco IOS XE Release 2.3.0 and later releases.

User-Defined Parent Class Limitation (for Hierarchical QoS)

On a Cisco ASR 1000 Series Router with hierarchical QoS and user-defined parent classes applied, each child policy must be a unique policy map. The use of a single child policy map in multiple instances in the definition of a user-defined parent class is not supported in Cisco IOS XE Release 2.3.0. For more details, see CSCsr56079.

Note The User-Defined Parent Class Limitation (for Hierarchical QoS) is no longer applicable in Cisco IOS XE Release 2.3.1 and later releases. The use of a single child policy map in multiple instances in the definition of a user-defined parent class is supported in these later releases.

User-Defined Parent Class Limitation (for Conditional Policer)

On a Cisco ASR 1000 Series Router with hierarchical QoS and user-defined parent classes applied, each child policy must use an unconditional policer (priority + policer). The use of conditional policers (priority x kbps) is not supported in these configurations in Cisco IOS XE Release 2.3.0. For more details, see CSCsy99583.

Tunnel Protection+ Priority Queuing Limitation

On a Cisco ASR 1000 Series Router configured with the tunnel protection command (which applies to DMVPN, VTI and GRE) and priority queuing (which applies to the outbound physical interface for the tunnel), it is not possible to oversubscribe the encryption coprocessor and maintain low latency traffic. A possible workaround is to apply both the crypto and priority qos policy to the physical interface. For more details, see CSCsy94190.

Starting with Cisco IOS XE Release 2.4.1, the platform ipsec llq qos-group command resolves the preceding limitation. See the "IPSec QoS Group-Based LLQ QoS" section.

Deny ACL Limitation for GET VPN

No more than 8 deny access control lists (ACLs) (a total of Key Server downloaded and group member local) are supported for Group Encrypted Transport VPN (GET VPN) in Cisco IOS XE Release 2.3.0. For more details, see CSCsy24144.

Limitation on Use of Deny Statements in QoS Classification

Large numbers of deny statements should not be used as access control entries (ACEs) in access control lists (ACLs) used for Quality of Service (QoS) classification in Cisco IOS XE Release 2.3.0. The number of deny statements and the order of these statements with other permit statements in an ACL determines the amount of content-addressable memory (TCAM) used, and there is no fixed number quantified as a limit for this configuration. For more details, see CSCsx16234.

Limitations and Restrictions in Cisco IOS XE Release 2.2.3

This section describes limitations and restrictions in Cisco IOS XE Release 2.2.3 and later releases.

DMVPN Limitation

In a very large Dynamic Multipoint VPN (DMVPN) network (for example, 1500 spokes connecting to a single hub), some of the tunnels may not be fully reflected in the hardware and may cause traffic drop on those tunnels. This condition is more likely to happen when users configure a very large number of spokes and toggle the interfaces between shut and no shut multiple times. When this condition occurs, perform shut/no shut on the specific spoke for which the hub does not have the entry in the hardware.

Scaling Limits for MLP

The supported scaling limits for Multilink PPP (MLP) per Cisco ASR 1000 Series chassis in Cisco IOS XE Release 2.2.3 and later releases are as follows:

•123 10 link bundles or

•245 5 link bundles or

•616 2 link bundles or

The maximum scaling limit for LFI is 1232 single link bundles.

If either the maximum number of bundles or maximum number of links are exceeded, the interface line rate may not be maintained. This limitation is especially applicable for configurations that have a high number of links per bundle and a high number of features enabled.

Limitations and Restrictions in Cisco IOS XE Release 2.2.1

This section describes limitations and restrictions in Cisco IOS XE Release 2.2.1 and later releases.

Cisco Firewall and WAAS Inter-Op Limitations and Restrictions

The Cisco Firewall and WAAS Interoperability feature is subject to the following limitations and restrictions for Cisco IOS XE Release 2.2.1:

•Only Generic Routing Encapsulation (GRE) redirect and return is supported. Layer 2 redirect and return is not supported.

•Certain platforms, such as the Cisco 2800 series, support an inbox network service module (WAAS-NM) that provides WAAS services. The Cisco ASR 1000 Series Routers do not support inbox network service modules; thus, the router will not support WAAS-NM.

Control Plane Policing (CoPP) Limitations and Restrictions

Control Plane Policing (CoPP) does not support match protocol l2tp and match protocol dhcp for Cisco IOS XE Release 2.2.1. CoPP does support packet matching with access lists, therefore you can police Layer 2 Tunneling Protocol (L2TP) and Dynamic Host Configuration Protocol (DHCP) packets matched by access lists. For example, L2TP and DHCP packets can be matched with access lists that check User Datagram Protocol (UDP) packet port number (1701 for L2TP, 67 and 68 for DHCP).

Flexible Packet Matching (FPM) Limitations and Restrictions

Flexible Packet Matching (FPM) support is subject to the following limitations and restrictions for Cisco IOS XE Release 2.2.1:

•Table 13 describes the functionality supported in the Raw FPM an d Basic FPM (Raw FPM+) modes in Cisco IOS XE Release 2.2.1:

Table 13 FPM Functionality Support by Mode
Mode	Supported Functionality
Raw FPM	•Supports Raw offset and bit pattern matching from L2 or L3 start •Protocol unaware •Match string pattern up to 32 bytes •Regular expression matching •Packet inspection depth: 256 bytes •·Maximal 32 classes are supported in a policy-map; 8 entries per class map
Basic FPM (Raw FPM+)	•PHDF nomenclature (for fixed length fields) •Support for building protocol stacks (for static header length only)

•Although Cisco IOS XE Release 2.2.1 does not support the traffic classification description file (TCDF), bittorrent, iis-unicode, ios-http-vuln and skype can be configured manually.

L2TP AAA Accounting Include NAS-PORT (VPI/VCI) Limitation

Limitations and Restrictions in Cisco IOS XE Release 2.1.1

This section describes limitations and restrictions in Cisco IOS XE Release 2.1.1 and later releases.

Up to 4K IPSec tunnels are supported in Cisco IOS XE Release 2.1.1.

Limitations and Restrictions in Cisco IOS XE Release 2.1.0

This section describes limitations and restrictions in Cisco IOS XE Release 2.1.0 and later releases.

Conditional Policing Feature of QoS Limitation

The Conditional Policing feature of Quality of Service (QoS) is not supported in Cisco IOS XE Release 2.1.0

Note Beginning with Cisco IOS XE Release 2.1.1 and later releases, the Conditional Policing feature of Quality of Service (QoS) is supported. This limitation does not apply to these later releases.

IPSec Anti-Replay Window Size Limitation

The maximum IPSec anti-replay window size supported in Cisco IOS XE Release 2.1.0 is 512.

Maximum Number of IPSec Tunnels Limitation

Up to 2k IPSec tunnels are supported in Cisco IOS XE Release 2.1.0.

Note Beginning with Cisco IOS XE Release 2.1.1 and later releases, up to 4K IPSec tunnels are supported supported. This 2K limitation does not apply to these later releases.

NBAR Protocol Support Limitation

Note Later releases of NBAR in Cisco IOS XE include support for additional protocols. For information about the NBAR protocol support per Cisco IOS XE release, see the following document: http://www.cisco.com/en/US/docs/ios/ios_xe/qos/configuration/guide/clsfy_traffic_nbar_xe.html

Network Based Application Recognition (NBAR) can only match the following protocols in Cisco IOS XE Release 2.1.0:

•CU-SeeMe

•Dynamic Host Configuration Protocol (DHCP)

•Domain Name System (DNS)

•Post Office Protocol (POP3)

•Telnet

•Secure HTTP

•Real Time Streaming Protocol (RTSP)

•Session Initiation Protocol (SIP)

•Skype (TCP-only)

•HTTP (no options including url and host)

•File Transfer Protocol (FTP)

•H.323

Police Command Limitation

When using a policer for service policies configured on Multilink PPP (MLP) bundles, the percent version of the police command should be used in Cisco IOS XE Release 2.1.0.

Scaling Limits for MLP

The supported scaling limits for Multilink PPP (MLP) in Cisco IOS XE Release 2.1.0 are as follows:

•16 10 link T1 bundles

•27 7 link T1 bundles

•40 5 link T1 bundles

•500 single link T1 bundles with LFI

Note Beginning with Cisco IOS XE Release 2.2.3 and later releases, the MLP scaling limits have been revised. For the revised scaling limits for Cisco IOS XE Release 2.2.3 and later releases, see "Scaling Limits for MLP" section.

–brief (Shows all crypto engines in the system.)

–configuration (Shows crypto engine configuration.)

–connections (Shows connection information.)

–qos (Shows QoS information.)

•The Cisco ASR 1000 Series Router does not currently support the display of send and recv error statistics using the show crypto ipsec sa identity command.

•The Cisco ASR 1000 Series Router does not support the clear and show crypto commands on the standby Route Processor (RP) by design.

•Counters in the show platform software ipsec fp active flow identifier n command are flagged for reset on read. You can use the show crypto ipsec sa command to obtain integral counters.

•The show access-list command output does not show a packet count matching the ACL.

•The Cisco ASR 1000 Series Router displays debugging information about the consumption of IPsec datapath memory; use the show platform hardware qfp act feature ipsec datapath memory command in privileged EXEC or diagnostic mode.

•The Cisco ASR 1000 Series Router displays debugging information about the crypto engine processor registers; use the show platform software ipsec f0 encryption-processor registers command in privileged EXEC or diagnostic mode.

Crypto Map Support

This section contains important notes about IPSec crypto map support on the Cisco ASR 1000 Series Router:

•The Cisco ASR 1000 Series Router does not currently support IPSec tunnel configuration for crypto maps with same IP address on both the tunnel interface and the physical interface. Configurations with different IP addresses are supported.

•A possible Embedded Services Processor (ESP) reload may occur if a large number (such as 2000) of crypto maps are removed simultaneously. When removing a large number of crypto maps, it is recommended you unconfigure 500 crypto maps at a time and wait 25 seconds between operations.

•The Cisco ASR 1000 Series Router does not support the show access-lists id command under crypto maps.

•The Cisco ASR 1000 Series Router does not currently support the interface range command when configuring crypto maps.

IPSec Packet Processing

This section contains important notes about IPSec packet processing on the Cisco ASR 1000 Series Router:

•Reloading an Embedded Services Processor (ESP) on the Cisco ASR 1000 Series Router may cause a few IPSec packets to drop before the initialization completes, but the traffic will resume after a brief interval.

•The Cisco ASR 1000 Series Router will not discard an incoming IP datagram containing a Payload Length other than 4 in the authentication header (AH). For example, a 96 bit authentication value plus the 3 32-bit word fixed portion for any non-null authentication algorithm will not be discarded.

•The Cisco ASR 1000 Series Router does not forward incoming authenticated packets with the IP option field set.

GET VPN Support

This section contains important notes about Group Encrypted Transport VPN (GET VPN) support on the Cisco ASR 1000 Series Router:

•To ensure normal traffic flow for a GET VPN configuration on a Cisco ASR 1000 Series Router, a Time Based Anti Replay (TBAR) window-size of greater than 42 seconds is recommended.

•The Cisco ASR 1000 Series Router does not currently support the TBAR statistics display in the show crypto gdoi gm replay command.

•The Cisco ASR 1000 Series Router does not currently support Easy VPN (EzVPN) and GET VPN on the same interface.

•When a Cisco ASR 1000 Series Router is to apply the same Group Domain of Interpretation (GDOI) crypto maps to two interfaces, you should use local addresses for the crypto maps. Non-local address configuration is not supported.

•The Cisco ASR 1000 Series Router does not currently support transport mode for TBAR.

•The Cisco ASR 1000 Series Router only supports the reassembly of post-fragmented GET VPN packets that are destined for the local Cisco ASR 1000 Series Router in the GET VPN network

•An enhancement is added to enable reassembly of IPsec transit traffic. This enhancement applies only to post-encryption fragmented IPsec packets. When this enhancement is enabled, IPsec will detect transit IPsec traffic and reassemble it before decryption. GET VPN transit IPsec traffic will be reassembled, decrypted, and forwarded to the destination. Non GET VPN transit IPsec traffic will be reassembled but not decrypted (because the ASR 1000 router is not the IPsec tunnel end point) and then forwarded to the destination.

To enable IPsec reassembly of transit traffic, use the platform ipsec reassembly transit command in global configuration mode. To disable IPsec reassembly of transit traffic, use the no form of this command.

platform ipsec reassembly transit

[no]platform ipsec reassembly transit

IPSec SSO and ISSU Support Notes

•The Cisco ASR 1000 Series Router supports stateful IPSec sessions on ESP switchover. During ESP switchover, all IPSec sessions will stay up and no user intervention is needed to maintain IPSec sessions.

•For an ESP reload (no standby ESP), the SA sequence number restarts from 0. The peer router drops packets that do not have the expected sequence number. User may need to explicitly reestablish IPSec sessions to work around this issue for systems that have a single ESP after an ESP reload. User may experience traffic disruption over the IPSec sessions in such cases for the duration of the reload.

•The Cisco ASR 1000 Series Router currently does not support Stateful Switchover (SSO) IPSec sessions on Route Processors (RPs). The IPSec sessions will go down on initiation of the switchover, but will come back up when the new RP becomes active. No user intervention is needed. User will experience traffic disruption over the IPSec sessions for the duration of the switchover, until the sessions are back up.

•The Cisco ASR 1000 Series Router currently does not support stateful ISSU for IPSec sessions. Before performing an ISSU, users must explicitly terminate all existing IPSec sessions or tunnels prior to the operation and reestablish them post ISSU. Specifically, users must ensure that there are no half-open or established IPSec tunnels present before performing ISSU. To do this, we recommend user do a interface shutdown in the case of interfaces that may initiate a tunnel setup, such as a routing protocol initiating a tunnel setup, or interfaces that have keepalive enabled or where there is an auto trigger for an IPSec session. Traffic disruption over the IPSec sessions during ISSU is obvious in this case.

Summarizing and restating the different caveats:

ESP - switchover (with standby ESP) : Stateful :

•IPSec sessions should be up. No user intervention needed.

ESP - Reload (No standby ESP) : Stateless :

•IPSec sessions will go down and come back up. Usually no user intervention is needed. However, user may need to explicitly reestablish Ipsec session again if anti replay is configured (sequence number checking).

RP - switchover (with standby RP) : Stateless :

•IPSec sessions will go down on RP switchover and should reestablish themselves when the new RP gains active role. No user intervention is needed.

ISSU (irrespective of chassis type): Stateless :

•User must explicitly terminate all IPSec sessions by shutting the interfaces, perform ISSU and then reestablish tunnels by enabling the interfaces. No other intervention needed.

Miscellaneous IPSec Support Notes

This section contains miscellaneous important notes about IPSec support on the Cisco ASR 1000 Series Router:

•The security association (SA) maximum transmission unit (MTU) calculation is based on the interface MTU instead of the IP MTU.

•The Cisco ASR 1000 Series Router currently supports a maximum anti-replay window value of 512. If you attempt to configure a value larger than 512, the Cisco ASR 1000 Series Router defaults back to 512 internally (although the display still shows your user-configured value).

•The Cisco ASR 1000 Series Router does not currently support nested SA transformation such as:

crypto ipsec transform-set transform-1 ah-sha-hmac esp-3des esp-md5-hmac

crypto ipsec transform-set transform-1 ah-md5-hmac esp-3des esp-md5-hmac

•The Cisco ASR 1000 Series Router does not currently support Cisco IOS Certificate Authority (CA) server features.

•The Cisco ASR 1000 Series Router does not currently support COMP-LZS configuration.

•For the Cisco ASR 1000 Series Router, when configuring GRE over IPSec, user is recommended to use only Tunnel protection mode on the Tunnel interface. Using crypto maps on both tunnel and physical interface to achieve GRE over IPSec is not the supported method of configuration.

•The Cisco ASR 1000 Series Router does not currently support VRF-Aware IPSec.

Important Notes in Cisco IOS XE Release 2.6.0:

This section describes important issues that you should be aware of for Cisco IOS XE Release 2.6.0 and later releases.

Per-User Attribute On PPP Virtual Access

In Cisco IOS XE Release 2.6.0 multiple instances of the per-user attribute `Cisco-Avpair=lcp:interface-config=<cmd>' is not supported.

For example:

Cisco-AVPair = lcp:interface-config=ip vrf forwarding vpngreen

Cisco-AVPair= lcp:interface-config=ip unnumbered loopback2

Should be configured like this in Cisco IOS XE Release 2.6.0:

Cisco-AVPair = lcp:interface-config=ip vrf forwarding vpngreen \nip unnumbered loopback2

"Multiple instances will be supported in Cisco IOS XE Release 2.6.1"

Legacy QoS Command Deprecation: Hidden Commands

To streamline Cisco IOS QoS (quality of service), certain commands are being hidden. Although these commands are available in Cisco IOS XE Release 2.6, the CLI interactive help does not display them. If

you attempt to view a command by entering a question mark at the command line, the command does not appear. However, if you know the command syntax, you can enter it. The system will accept the command and return a message explaining that it will soon be removed. These commands will be completely removed in a future release, which means that you will need to use the appropriate replacement commands.

For more information, see the following document:

http://www.cisco.com/en/US/docs/ios/ios_xe/qos/configuration/guide/legacy_qos_cli_deprecation_xe.html

VRF-Aware NAT

Dependency of NAT on VFR

ASRNAT will not handle fragmented packets unless VFR is configured on all NAT interfaces. VFR will automatically be configured when NAT is configured, but users must "not" manually unconfigure VFR on NAT interfaces as NAT cannot process the fragmented packets and out-of-order fragments correctly.

Important Notes in Cisco IOS XE Release 2.5.0:

This section describes important issues that you should be aware of for Cisco IOS XE Release 2.5.0 and later releases.

Embedded Packet Capture

The Embedded Packet Capture (EPC) feature is not functional and not supported for the Cisco ASR 1000 Series Routers.

QoS - Policing Support for GRE Tunnels

When queuing feature on the GRE tunnel interface is not supported with crypto configured on the physical interface.

QoS: QoS support for GRE/sVTI Tunnel

With IOS XE 2.5.0, the Cisco ASR 1000 Router Series supports Quality-of Service (QoS) applied to

•A GRE or sVTI tunnel with policing and marking only for INGRESS traffic

•A GRE or sVTI tunnel with 2-level hierarchy allowing queuing on the second level for EGRESS traffic

When there are multiple egress physical interfaces for a tunnel, and the tunnel target physical interface changes as a result of tunnel target destination route change, either manually by user configuration or by routing protocol, IOS will not prevent the tunnel traffic from moving to an alternate egress physical interface.

However, in IOS XE 2.5.0, QoS tunnel move feature is not supported. When tunnel traffic moved to an alternate egress physical interface, tunnel QoS policy may enter a suspended state. At this point, the tunnel QoS policy will have to be removed and reapplied to the tunnel interface for it to take effect.

In addition, queuing features on the GRE tunnel interface are not supported when IPSec is configured on the physical interface.

In a GRE over IPsec configuration with a crypto map configured on the physical interface, traffic shaping on the GRE tunnel interface is not supported. The workaround is to use sVTI (tunnel protection with tunnel mode IPsec).

VRF-Aware NAT

Integrating NAT with MPLS VPNs

Prerequisites for integrating NAT with MPLS VPNs

Before performing the tasks in this module, you should be familiar with the concepts described in the "Configuring NAT for IP Address Conservation" module.

All access lists required for use with the tasks in this module should be configured prior to beginning the configuration task. For information about how to configure an access list, see the "IP Access List Sequence Numbering" document at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122s/122snwft/release/122s14/fsacl

seq.htm

Note Note If you specify an access list to use with a NAT command, NAT does not support the commonly used permit ip any command in the access list.

Restrictions for Integrating NAT with MPLS VPNs

•The following functionality is not supported for VRF-Aware NAT:

–VPN to VPN translations. In other words, VRF cannot be applied on the NAT outside interface.

–Translation of multicast packets

–Translations with inside destinations

–Reversible route maps

–MIBs

–MPLS traffic engineering

•Configuring inside dynamic translations defined with outside interface mappings is not supported.

•Configuring inside static translations with interface mappings is not supported. The following commands, which do not include VRF, are not supported:

–ip nat inside source static esp local-ip interface type number

–ip nat inside source static local-ip global-ip route-map name

–ip nat inside source static local-ip interface type number

–ip nat inside source static tcp local-ip local-port interface type number global-port

–ip nat inside source static udp local-ip local-port interface type number global-port

Dependency of NAT on VFR

VRF-Aware NAT

Dependency of NAT on VFR

ASRNAT will not handle fragmented packets unless VFR is configured on all NAT interfaces and environments in Cisco IOS XE Release 2.2.1. VFR will automatically be configured when NAT is configured, but users must "not" manually unconfigure VFR on NAT interfaces as NAT cannot process the fragmented packets and out-of-order fragments correctly.

Important Notes in Cisco IOS XE Release 2.1.1

This section describes important issues that you should be aware of for Cisco IOS XE Release 2.1.1 and later releases.

Startup Configuration File Backup

As a matter of routine maintenance on any Cisco router, users should backup the startup configuration file by copying the startup configuration file from NVRAM onto one of the router's other file systems and, additionally, onto a network server. Backing up the startup configuration file provides an easy method of recovering the startup configuration file in the event the startup configuration file in NVRAM becomes unusable for any reason.

For users using any Cisco ASR 1000 Series Router with a single RP, including any Cisco ASR 1002 or Cisco ASR 1004 Router, backing up the startup configuration file onto another router file system is especially important due to CSCsq70140, which is documented in the Caveats section of these release notes. The workaround for users who run into this caveat is to replace the startup configuration file in NVRAM with a backup copy of the startup configuration file on the router; therefore, customers who have backed up their startup configuration files onto the router will be ready to resolve these caveats if they occur on their Cisco ASR 1000 Series Routers using a single RP.
