Upgrading the Switch Fabric

Step 10 See the next section, Verifying the Upgrade.

Note Additional information is available on the Cisco TAC website. Refer to the Cisco 12000 Series Internet

Router Upgrade Procedure document.

Verifying the Upgrade

To verify that the upgraded switch fabric is operating properly, follow these steps:

Step 1 Perform all the steps listed in the “Upgrading the Switch Fabric” section on page 19. If there is a

mismatch between the older and newer switch fabric cards, an error message appears on the console.

Step 2 Run the show gsr command to see if the new switch fabric cards are detected by the system.

Note The show gsr command output varies slightly between each switch fabric card set.

Step 3 See the “Troubleshooting the Switch Fabric” section on page 22 if you encounter problems. Also review

the next section, Post-Upgrade Considerations.
