    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 system software abort in-service-upgrade (ICU) for more information.
