| Feature | Description |
|---|---|
|
IP Addresses and Services |
|
|
This release introduces the handle-jumbo-packet configuration command under the dhcp ipv6 mode. This command enables processing of incoming DHCPv6 packets greater than 1280 bytes and upto 12,800 bytes in size. Prior to this release, the router discarded incoming DHCPv6 packets greater than 1280 bytes. The newly introduced command is: |
|
|
Custom Prefix Length Selection |
By default, /48 prefix length is inserted in the LEM memory. This feature allows you to choose a custom IPv6 prefix length to be inserted into the largest exact match (LEM) memory. This feature introduces the hw-module fib scale ipv6 custom-lem command. |
|
L2VPN and Ethernet Services |
|
|
Control word is now supported and enabled by default in ELAN mode. If the control-word-disable command is not configured, ensure to configure it under EVPN or EVI configuration mode before an upgrade to avoid inconsistent behaviour with routers before this release. If you want to enable control-word command for EVPN Bridging feature, then you must configure it only when both the endpoints run Release 7.4.1 or later. |
|
|
PPPoE Traffic-Based Load Balance using Flow-Aware Transport Labels |
This feature allows you to load balance the incoming PPPoE traffic received based on the inner PPPoE payload, source and destination IPv4 or IPv6 header. When you enable this feature, the router generates a unique Flow-Aware Transport (FAT) label for the incoming traffic based on inner IPv4 or IPv6 headers and uses the FAT labels for load balancing the PPPoE traffic. This feature introduces the hw-module profile load-balance algorithm PPPoE command. |
|
VLANs separated by a comma are called VLAN lists. This feature allows you to configure a VLAN list on the L2 sub interface. VLAN-IDs of up to 9 are supported, per VLAN list. This feature overrides any limit set on the number of customers that can be supported in an Ethernet network. |
|
|
Maximum MAC addresses on UNI port |
This feature introduces MAC limit and MAC limit action on bridge port, which was earlier only available on bridge domain. This feature supports:
Thus, allowing you to limit the maximum number of clients connected to a bridge on a site. |
|
L3VPN |
|
|
This feature allows ISPs to provide MPLS Layer 3 VPN services to their end customers where the routing boundaries for a customer are spread across different geographical locations. Separate autonomous systems with autonomous system boundary routers (ASBRs) from different service providers can communicate by exchanging VPN-IPv4 addresses or IPv4 routes and MPLS labels. This feature provides better scalability as it requires only one BGP session to exchange all VPN prefixes between the ASBRs. |
|
|
Modular QoS |
|
|
Prior to this functionality, when configuring policers, the only available option for policer rates was bit-rate measured in units of bits per second (bps). With this release, you can configure policer rates in units of packets per second (pps) as well. pps-based policer is critical in fending off malicious attacks—when attackers target your specific resources with a vast amount of traffic that contain higher number of packets, but move at a slower packet rate. Protection from such attacks is possible because pps-based policers ensure that regardless of the packet size and rate, the policer only accepts a fixed number of packets per second. This functionality modifies the police rate command. |
|
|
Multicast |
|
|
This feature allows encapsulation of multicast packets using GRE tunnels, thereby enabling transport of multicast packets securely between source and destination routers located in different IP clouds. |
|
|
Rosen draft (profile 0) is a widely used MVPN model and uses GRE tunnels to securely transmit multicast traffic between the PE routers. It also enables ease of deployment by using the Protocol-Independent Multicast (PIM) protocol between edge routers (PE) and hosts (CE), and between PE routers that are running in VRF mode. |
|
|
With this feature, the router sends a PIM hello message with a special PIM DR priority value on a multi-access LAN. The router with this special DR priority value is always elected as the designated router. The traffic now flows in the same path even when a new router is added. This feature introduces the sticky-dr command. |
|
|
Programmability |
|
|
This tool provides a quick reference of IOS XR CLIs and the corresponding YANG data model that could be used. New command introduced for this feature: yang describe. |
|
|
Unified models are CLI-based YANG models that are designed to replace the native schema-based models. UM models are generated directly from the IOS XR CLIs and mirror them in several ways. This results in improved usability and faster adoption of YANG models. You can access the new unified models from the Github repository. |
|
|
The network orchestrator is a central point of management for the network and typical workflow involves synchronizing the configuration states of the routers it manages. Loading configurations for comparing the states involves unnecessary data and subsequent comparisons are load intensive. This feature synchronizes the configuration states between the orchestrator and the router using a unique commit ID that the router maintains for each configuration commit. The orchestrator retrieves this commit ID from the router using NETCONF Remote Procedure Calls (RPCs) to identify whether the router has the latest configuration. |
|
|
Routing |
|
|
The multihop BFD over BVI feature introduces support for multihop BFD over Bridge Group Virtual Interface (BVI). A multihop BFD session can be set up between two endpoints that have IP connectivity. This session is set up between a unique source-destination address pair provided by the client. This feature allows you to extend BFD on arbitrary paths. These arbitrary paths can span multiple network hops, thereby detecting link failures. |
|
|
This feature provides the benefits of both BOB and BLB. This feature enables you to configure both BFD over bundle (BOB) and BFD over logical bundle (BLB) over physical bundle interfaces and subinterfaces. BOB functionality allows you to detect failures in physical bundle interfaces. BLB functionality allows you to detect failures in the client protocols configured on the subinterfaces. |
|
|
This feature enables RIP as the IGP of your network. RIP broadcasts UDP data packets to exchange routing information in networks that are flat rather than hierarchical, reducing network complexity and network management time. |
|
|
Segment Routing |
|
|
Advertisement of Link Attributes for IS-IS Flexible Algorithm |
Link attribute advertisements used during Flexible Algorithm path calculation must use the Application-Specific Link Attribute (ASLA) advertisements, as defined in IETF draft draft-ietf-lsr-flex-algo. This feature introduces support for ASLA advertisements during IS-IS Flexible Algorithm path calculation. |
|
This feature extends the current Microloop Avoidance functionality to support OSPF. |
|
|
By default, if an SR Policy becomes invalid (for example, if there is no valid candidate path available), traffic falls back to the native SR forwarding path. In some scenarios, a network operator may require that certain traffic be only carried over the path associated with an SR policy and never allow the native SR LSP to be used. This feature allows the SR policy to stay up in the control plane (to prevent prefixes mapped to the SR policy from falling back to the native SR LSP) but drop the traffic sent on the SR policy. |
|
|
Per-Flow Automated Steering: L3 / L2 BGP Services + BSID Steering |
This feature introduces support for BGP VPNv6 (6VPE) and BGP EVPN (single-home/multi-homed) over PFP, labeled traffic (Binding SID as top-most label in the stack) steering over per-flow policy (PFP). An ingress QoS policy applied to an input interface is used to classify flows and set corresponding MPLS experimental values. |
|
This feature adds support for L2VPN service Label Edge Router (LER) and BGP PIC for Layer 3 BGP services when SR ECMP-FEC Optimization is enabled. |
|
|
Flexible Algorithm allows for user-defined algorithms where the IGP computes paths based on a user-defined combination of metric type (path optimization objective) and constraint. This feature add support for TE metric as a metric type for IS-IS Flexible Algorithm. This allows the TE metric, along with IGP and delay metrics, to be used when running shortest path computations. |
|
|
By default, the SR-TE process prefers the protected Adj-SID of the link if one is available. If there is no protected Adj-SID available, the policy will come up with unprotected Adj-SID. This feature allows you to specify the Adj-SID protection behavior of the SR-TE process to prefer the protected or unprotected Adj-SID, or to use only the protected or unprotected Adj-SID. |
|
|
This feature allows you to define thresholds above the measured delay that is considered “anomalous” or unusual. When this threshold is exceeded, an anomaly (A) bit/flag is set along with link delay attribute that is sent to clients. |
|
|
Licensing |
|
|
You can now use Smart transport to communicate with CSSM. Smart transport is a transport method where a Smart Licensing (JSON) message is contained within an HTTPs message, and exchanged between a product instance and CSSM, to communicate. The following Smart transport configuration options are available:
|
|
|
With this feature, you can use data models for all the smart licensing operations such as registering your device with a token, renewing token ID, deregistering device to remove the software entitlements and so on using NETCONF remote procedure calls (RPCs). The following data models are introduced:
You can access these data models from the Github repository. |
|
|
Essential and Advantage smart licenses in a combined entitlement |
With this release, the Advanced licenses are now referred to as the Advantage licenses, without essential entitlement. Also, a new license model – Advantage with Essentials, has been introduced that contains both Essential and Advantage licenses as a combined entitlement in a single PID. This simplifies the license procurement and management effort by eliminating the need to procure separate PIDs for Essential and Advantage licenses. |
|
System Setup |
|
|
A maximum of 900MB of disk space is used to store all rollback points. You can delete older rollback points to make space for newer or smaller rollback points such as, SMUs. The following NCS 540 variants allow up to 900MB of disk space for rollback points:
This feature introduces the following commands:
The following command is updated to include the keyword, oldest n:
|
|
|
There is no longer a need to copy an ISO image on the router to install XR7. Starting with this release, you can fetch an ISO or tar file of RPMs over the network as part of Install operation. You can also directly install the image from an FTP or HTTP server that hosts the image. The install source can also be a URL to a tar file (a file with extensions, .tar, .tgz, or .tar.gz). This feature modifies the following commands:
|
|
|
System Security |
|
|
This release introduces:
Use the |
|
|
Telemetry |
|
|
Streaming huge telemetry data can create congestion in the network. With this feature, you can use the regular expression (regex) keys in the sensor path configuration on the router. The keys limit the amount of data that can be streamed, thereby ensuring better bandwidth utilization. |
|
The following features are supported only on N540-28Z4C-SYS-A/D, N540X-16Z4G8Q2C-A/D, N540-12Z20G-SYS-A/D and N540X-12Z16G-SYS-A/D variants.
| Feature | Description |
|---|---|
|
System Security |
|
|
Before this release, the Integrity Measurement Architecture (IMA) appraisal created an audit log when any executable on your system was modified without authorization. In this scenario, you could still open the compromised executable. In this release, the IMA enforces its appraisal instead of simply logging an issue. It does so by blocking any operation (open or run) for a compromised executable. This enforced mode of appraisal ensures a higher level of trust and security at runtime. |
|
|
CiscoSSH |
CiscoSSH leverages OpenSSH implementation, by using the Linux TCP/IP stack to transmit and receive SSH packets over the management Ethernet interface and line card interfaces on the router. CiscoSSH provides additional security features like FIPS compliance and X.509 digital certification. It supports packet path features like MPP, ACL and VRF support, and ensures interoperability with various existing SSH implementations. |
|

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.
The upgrade document for N540-24Z8Q2C-SYS, N540X-ACC-SYS, and N540-ACC-SYS variants is available along with the software image in NCS540-docs-7.4.1.tar file.
The upgrade document for N540-28Z4C-SYS-A/D, N540-12Z20G-SYS-A/D, N540X-12Z16G-SYS-A/D, and N540X-16Z4G8Q2C-A/D variants is available along with the software image in NCS540l-docs-7.4.1.tar file.
Use user-class Option 'xr-config' Instead Of 'exr-config' To Provision ZTP
In Cisco IOS XR Release 7.3.1 and earlier, the system accepts the device sending user-class = "exr-config"; however starting Cisco IOS XR Release 7.3.2 and later, you must use only user-class = "xr-config".
In Cisco IOS XR Release 7.3.2 and later, use:
host cisco-rp0 {
hardware ethernet e4:c7:22:be:10:ba;
fixed-address 172.30.12.54;
if exists user-class and option user-class = "iPXE" {
filename = "http://172.30.0.22/boot.ipxe";
} elsif exists user-class and option user-class = "xr-config" {
filename = "http://172.30.0.22/scripts/cisco-rp0_ztp.sh";
}
