Troubleshooting Unified ISSU Problems


If the unified ISSU procedure stops progressing:

  1. Open a new session on the master Routing Engine and issue the request system software abort in-service-upgrade command.

  2. Check the existing router session to verify that the upgrade has been aborted.

    An “ISSU: aborted!” message is provided. Additional system messages provide you with information about where the upgrade stopped and recommendations for the next step to take.

See request chassis cluster in-service-upgrade abort (ISSU) for more information.
