What's New in Cisco IOS XR Release

Cisco is continuously enhancing the product with every release and this section covers a brief description of key features and enhancements. It also includes links to detailed documentation, where available.

Feature Description

Multicast

mLDP Loop-Free Alternative Fast Reroute

In the event of link failure, this feature enables the router to switch traffic quickly to a precomputed loop-free alternative (LFA) path by allocating a label to the incoming traffic. Thus minimizes the traffic loss ensuring fast convergence.

Caveats

Caveats describe unexpected behavior in Cisco IOS XR Software releases. Severity-1 caveats are the most critical caveats; severity-2 caveats are less critical.

This section contains caveats that are generic to the Cisco IOS XR Software Release and those specific to the Cisco CRS-1 router and the Cisco CRS-3 router.

Determining Installed Packages

To determine the version of Cisco IOS XR Software packages installed on your router, log in to the router and enter the show install committed summary command:

Firmware Support

To check the firmware code running on the Cisco CRS Router, run the show fpd package command in admin mode.


Note

The show command output lists supported and EOL hardware PIDs. To know the PIDs that are supported in this release, see the Supported Hardware section in this Release Notes.

Other Important Information

  • Starting with Cisco IOS XR Release 6.7.2, the output for show mpls traffic-eng tunnels xx role head command is missing protocol and area ID information for path-option dynamic tunnels in area 0.

  • Starting with Cisco IOS XR Release 6.3.1, the SNMP walk for any OSPF Metric OID returns only the metric of the highest area ID from either MADJ interface or primary interface. That is, if the highest area ID is for MADJ interface then the OID returns the MADJ interface metric, or if the highest area ID is for primary interface, it will return primary interface metric. Prior to this release, the OID would return primary interface metric and highest area ID MADJ interface metric.

  • From Release 6.0, the onePK toolkit is not supported.

  • Default timestamp setting—The timestamp prompt that precedes console output is enabled by default. To disable the timestamp prompt, use the no service timestamp command. For more information, refer to the Cisco IOS XR System Management Command Reference for the Cisco CRS Router .

  • Country-specific laws, regulations, and licenses—In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.

  • Field replacable unit (FRU) removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RP) follow the instructions provided by Cisco to avoid impact to traffic. See the Cisco IOS XR Getting Started Guide for the Cisco CRS Router for procedures.

  • Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration for your purpose.

  • mpls traffic engineering igp-intact command—This command must be used only when policy based tunnel selection is configured for all tunnels originating on the device. This CLI needs to be turned on under IGP (OSPF/ISIS) under the respective AFI.

  • The following TE Path option attribute commands are not supported on the Cisco CRS-1 Series Router:

    • affinity location set

    • affinity location type

    • affinity program

    • affinity self

  • BFD IPv6 UDP Checksum Calculation—Starting Cisco IOS XR Software Release 3.9, you turn the BFD IPv6 UDP checksum calculation on and off:

    • To disable the BFD IPv6 UDP checksum calculation: 

      RP/0/RP0/CPU0:router(config)#bfd

RP/0/RP0/CPU0:router(config-bfd)#ipv6 checksum disable

RP/0/RP0/CPU0:router(config-bfd)#end

    • To enable BFD IPv6 UDP checksum calculation: 

      
RP/0/RP0/CPU0:router(config)#bfd

RP/0/RP0/CPU0:router(config-bfd)#no ipv6 checksum disable

RP/0/RP0/CPU0:router(config-bfd)#end

  • When upgrading a system from a release prior to 3.8.4, the MAC address assigned to physical interfaces changes. This is required because prior to Cisco IOS XR Software Release 3.8.4 the MAC address assigned to the bundle interface was taken from the first member's MAC address. If this bundle member is removed from the bundle, the bundle gets a new MAC address, which results in traffic loss due to ARP resolution. Beginning in Cisco IOS XR Software Release 3.8.4, a pool of MAC addresses are assigned to the bundle interfaces by the bundlemgr process during bundle interface creation.

  • Deactivation of os-mbi dependent (Nonreload) SMU fails—Backing out the non reload os-mbi SMU fails because deactivation runs out of memory (activation did not release some memory, which stayed at 38 MB). This failure to activate or deactivate the SMU due to insufficient SP resources impacts SP cards on CRS.

  • When configuring the Label Distribution Protocol (LDP) graceful restart (GR) process in a network with multiple [link and/or targeted] LDP hello adjacencies with the same neighbor, make sure that GR is activated on the session before any hello adjacency times out due to neighbor control plane failures. One way of achieving this is by configuring a lower session hold time between neighbors such that session time out always occurs before hello adjacency can time out. Cisco recommends setting LDP session hold time using the following formula:

    LDP session hold time <= (Hello hold time - Hello interval) * 3

    This means that for default values of 15/5 seconds respectively for the link Hello hold time and the Hello interval, the LDP session hold time should be set to 30 seconds or less.

    For more information, refer to the Implementing MPLS Label Distribution Protocol on Cisco IOS XR Software section of the MPLS Configuration Guide for the Cisco CRS Routers.

    DWDM Configuration Management


    Note

    This section describes the new DWDM configuration requirements in Cisco IOS XR 3.9.0 and later releases. It does not describe all updates to the DWDM feature. For more information about DWDM configuration, refer to the Configuring Dense Wavelength Division Multiplexing Controllers on Cisco IOS XR Software module in the Cisco IOS XR Interface and Hardware Component Configuration Guide for the Cisco CRS Router.

    Cisco IOS XR Software Release 3.9.0 introduced new commands in addition to an important change to the default laser state for all of the DWDM physical layer interface modules (PLIMs) supported on the Cisco CRS-1 and CRS-3 routers, which impacts the required configuration to support those cards.

    This change affects all models of the following hardware on the Cisco CRS-1 router:

    • Cisco 1-Port OC-768c/STM-256c DWDM PLIM

    • Cisco 4-Port 10-Gigabit Ethernet DWDM PLIM

    This change affects all models of the following hardware on the Cisco CRS-3 router:

    • Cisco 1-Port 100GE OTU4 IPoDWDM PLIM

    • Cisco 4-Port 40-GE OTU3 OTN/LAN PLIM

    • Cisco 2-Port 40-GE OTU3 OTN/LAN PLIM

    The g709 fec high-gain and g709 fec long-haul commands are added under DWDM configuration to configure the new high-gain FEC mode and long-haul FEC mode for Cisco 1-Port 100GE OTU4 IPoDWDM PLIM.

    The following is an example of configuring the g709 fec high-gain command under DWDM configuration to configure the new high-gain FEC mode: 

    
RP/0/RP0/CPU0:router# configure 
RP/0/RP0/CPU0:router(config)# controller dwdm <>
RP/0/RP0/CPU0:router(config)# g709 fec high-gain
RP/0/RP0/CPU0:router(config)# commit

    The following is an example of configuring the g709 fec long-haul command under DWDM configuration to configure the new long-haul FEC mode: 

    
RP/0/RP0/CPU0:router# configure 
RP/0/RP0/CPU0:router(config)# g709 fec long-haul
RP/0/RP0/CPU0:router(config)# commit

    Upgrading Cisco IOS XR Software

    Cisco IOS XR Software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).

    Software packages are installed from package installation envelope (PIE) files that contain one or more software components.

    Before starting the software upgrade, use the show install health command in the admin mode. This command validates if the statuses of all relevant parameters of the system are ready for the software upgrade without interrupting the system.

    The upgrade document is available along with the software images.

    The upgrade document CRS_Upgrade_Downgrade_MOP_6.7.4.pdf is available along with the Release 6.7.4 software images downloaded from the software download page.

    Cisco Software Manager (CSM) application provides an intuitive user interface to manage Cisco IOS XR installations, with pre-installation and post-installation checks and reports. CSM helps manage the process of software maintenance upgrades (SMUs) and service packs (SPs) on devices that run the Cisco IOS XR Software.

    For information on how to use CSM, see Cisco Software Manager User Guide.
