Network Convergence System 5500 Series Routers


Note

Cisco IOS XR Release 7.9.2 is an Extended Maintenance Release of Cisco IOS XR Release 7.9.1 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.

What's New in Cisco IOS XR Release 7.9.2

Cisco IOS XR Release 7.9.2 is an extended maintenance release for Cisco NCS 5500 Series routers. There are no new software features or hardware introduced in this release.

For more details on the Cisco IOS XR release model and associated support, see Guidelines for Cisco IOS XR Software.

Behavior Changes

  • Prior to Cisco IOS XR release 7.2.1, a segment of an explicit segment list can be configured as an IPv4 address (representing a Node or a Link) using the index indexaddress ipv4 address command.

    Starting with Cisco IOS XR release 7.2.1, an IPv4-based segment (representing a Node or a Link) can also be configured with the new index index mpls adjacencyaddress command. The configuration is stored in NVRAM in the same CLI format used to create it. There is no conversion from the old CLI to the new CLI.

    Starting with Cisco IOS XR release 7.9.1, the old CLI has been deprecated. Old configurations stored in NVRAM will be rejected at boot-up.

    As a result, explicit segment lists with IPv4-based segments using the old CLI must be re-configured using the new CLI.

    There are no CLI changes for segments configured as MPLS labels using the index index mpls label label command.

  • If you are on a release before Cisco IOS XR Release 7.4.1, you can configure SR-ODN with Flexible Algorithm constraints using the segment-routing traffic-eng on-demand color color dynamic sid-algorithm algorithm-number command.

    Starting with Cisco IOS XR release 7.4.1, you can also configure SR-ODN with Flexible Algorithm constraints using the new segment-routing traffic-eng on-demand color color constraints segments sid-algorithm algorithm-number command.

    From Cisco IOS XR Release 7.9.1, the segment-routing traffic-eng on-demand color color dynamic sid-algorithm algorithm-number command is deprecated. Previous configurations stored in NVRAM will be rejected at boot-up.

    Hence, for Cisco IOS XR Release 7.9.1, you must reconfigure all SR-ODN configurations with Flexible Algorithm constraints that use the on-demand dynamic sid-algorithm with the on-demand constraints command.

Determine Firmware Support

Use the show hw-module fpd command in EXEC and Admin mode to view the hardware components with their current FPD version and status. The status of the hardware must be CURRENT; Running and Programed version must be the same.


Note

You can also use the show fpd package command in Admin mode to check the fpd versions.

This sample output is for show hw-module fpd command from the Admin mode: 

sysadmin-vm:0_RP0# show hw-module fpd

Important Notes

  • 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.

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

  • If you use a TAR package to upgrade from a Cisco IOS XR release prior to 7.x, the output of the show install health command in admin mode displays the following error messages: 

sysadmin-vm:0_RSP0# show install health
. . .
ERROR /install_repo/gl/xr -rw-r--r--. 1 8413 floppy 3230320 Mar 14 05:45 <platform>-isis-2.2.0.0-r702.x86_64

You can ignore these messages and proceed with the installation operation.

  • Quad configurations will be lost when you perform a software downgrade on a NCS-55A1-48Q6H device from IOS XR Release 7.5.1 onwards to a release prior to IOS XR Release 7.5.1 due to non-backward compatibility change. The lost configuration can be applied manually after the downgrade.


    Note

    A quad is a group of four ports with common speeds, 1G/10G or 25G. You can configure the ports speed for a quad by using the hw-module quad command.

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.
