Cisco IOS XR Release 7.4.2 is an Extended Maintenance Release of Cisco IOS XR Release 7.4.1 for Cisco NCS 5500 Series routers. For more details on the Cisco IOS XR release model and associated support, see Guidelines for Cisco IOS XR Software. |
Software Features Introduced and Enhanced
To learn about features introduced in other Cisco IOS XR releases, select the release from the What's new page.
Unless specified the following features are not supported on the Cisco 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native or compatibility mode.
To enable the native mode on Cisco NCS 5500 series routers having Cisco NC57 line cards, use the hw-module profile npu native-mode-enable command in the configuration mode. Ensure that you reload the router after configuring the native mode.
Feature | Description |
---|---|
Telemetry |
|
Telemetry Support for OpenConfig Interfaces, IPv4 and IPv6 Addresses and State |
This feature provides GNMI and GRPC telemetry support for the following openconfig-if-ip.yang sensor paths. Previously, only NETCONF edit-config, get-config and get operations were supported. With this new feature, telemetry polling at a cadence or on-change can be retrieved for IPv4 and IPv6 data.
You can access this data model from the Github repository. |
L2VPN and Ethernet Services |
|
Ingress Storm control (BUM) policers |
This feature helps to rate limit ingress broadcast, multicast, unknown-unicast (BUM) traffic as per the configured threshold. It is now supported on routers that have Cisco NC57 line cards with external TCAM that are installed and operating in native mode. |
With this feature, you can configure a Bridge Group Virtual Interface (BVI) and request a DHCP IPv6 address on the BVI. This configuration allows your customer's device to have initial connectivity to your network without user intervention in the field. This feature is now supported on Cisco NCS 5700 series fixed-port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native mode. |
|
MAC Loop Release Prevention |
This feature helps reduce network congestion and avoid traffic loss by shutting down a port after it reaches the configured number of MAC moves within the specified move interval. You can configure this feature at the bridge-domain level using the mac secure command. This feature is now supported on routers that have Cisco NC57 line cards installed and operate in native and compatibility modes. |
This feature enables you to seamlessly migrate the PE nodes from VPWS to EVPN-VPWS service without disruption in traffic. Such a migration offers your service providers the option to use VPWS or EVPN-VPWS services on PE nodes This feature introduces the vpws-seamless-integration command. |
|
Segment Routing |
|
SR Policy Path Protection |
This feature enables path protection for SR policies. It allows you to configure an SR policy with working (active) and protect (backup) candidate paths pre-programmed in the forwarding. You can monitor these candidate paths using SR Policy Liveness Monitoring probes. When the head-end detects a liveness failure on the working candidate path, it triggers a switchover to the protect candidate path. |
QoS |
|
Cisco NC57 Native Mode: 802.1P marking |
This feature marks priority code point (PCP) and drop eligible indicator (DEI) fields on VLAN-tagged ethernet frames egressing out of the Layer 3 subintentace and helps achieve differentiated QoS in the network based on PCP and DEI marking. This feature is now supported for multicast traffic on routers that have the Cisco NC57 line cards installed and operate in the native mode. |
This feature marks packets instead of dropping them when the average queue length exceeds a specific threshold value, ensuring timely and efficient end-to-end congestion notification leading to fewer packet drops. This feature is now supported on routers that have Cisco NC57 line cards installed and operate in the native mode. |
Hardware Introduced
This release introduces the following new hardware:

Other Important Information
-
The total number of bridge-domains (2*BDs) and GRE tunnels put together should not exceed 1518.
Here the number 1518 represents the multi-dimensional scale value.
-
The offline diagnostics functionality is not supported in NCS 5500 platform. Therefore, the hw-module service offline location command will not work. However, you can use the (sysadmin)# hw-module shutdown location command to bring down the LC.
Supported Transceiver Modules
To determine the transceivers that Cisco hardware device supports, refer to the Transceiver Module Group (TMG) Compatibility Matrix tool.
Supported Modular Port Adapters
For the compatibility details of Modular Port Adapters (MPAs) on the line cards, see the datasheet of that specific line card.
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).
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.
Note |
You can ignore these messages and proceed with the installation operation. |
Production Software Maintenance Updates (SMUs)
A production SMU is a SMU that is formally requested, developed, tested, and released. Production SMUs are intended for use in a live network environment and are formally supported by the Cisco TAC and the relevant development teams. Software bugs identified through software recommendations or Bug Search Tools are not a basis for production SMU requests.
For information on production SMU types, refer the Production SMU Types section of the IOS XR Software Maintenance Updates (SMUs) guide.
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";
}
}
