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
                                                                     FPD Versions

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.

  • BGP-Labeled Unicast (LU) Prefix-Independent Convergence (PIC) auto-protection feature may cause equal cost multipath (ECMP) FEC NPU resource exhaustion on BGP peering devices for IPv4/IPv6 addresses. From Cisco IOS XR Release 7.8.2 onwards, the auto-protection feature for BGP-LU multipath PIC is disabled by default. To enable this feature, use the hw-module fib bgp-mp-pic auto-protect enable command. After executing the command, you must reload the router.For more information, see BGP-LU Multipath PIC with Auto Protection section in BGP Prefix Independent Convergence chapter in BGP Configuration Guide for Cisco NCS 5500 Series Routers.

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.

Cisco IOS XR MIBs

To determine the MIBs supported by platform and release, refer to the Cisco IOS XR MIBs tool.

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
ERROR /install_repo/gl/xr -rwxr-x---. 1 8413 165 1485781 Mar 14 06:02 <platform>-k9sec-3.1.0.0-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.
