Commit the New Image to the VSS Standby Chassis
When the active chassis is successfully running the new image in the SSO redundancy state, you can
enter either the issu acceptversion command to stop the rollback timer and hold this state indefinitely,
or the issu commitversion command to continue with the eFSU. To continue, enter the issu
commitversion command to upgrade the VSS standby chassis and complete the eFSU sequence. The
VSS standby chassis reboots, reloads with the new image, and initializes as the VSS standby chassis in
the SSO redundancy state, running the new image. This step is complete when the chassis configuration
is synchronized, as indicated by the “Bulk sync succeeded” message.

Verify That the Upgrade is Complete
You can now enter the show issu state detail command and the show redundancy command to check
the results of the eFSU. In this example, both chassis are now running the “newversion” image,
indicating that the eFSU was successful. Because the eFSU has completed, the two chassis will be
once again in the ISSU Init Version state, as they were before the eFSU was initiated.
