Outlines the criteria for stopping self-recovery and opening a Cisco Support case for repeated ROMMON recovery, boot failures, synchronization issues, install inconsistencies, failed updates, unexpected reloads, or persistent recovery and rollback problems.


Stop self-recovery and open a Cisco Support case when any of these conditions applies:

  • The device repeatedly returns to ROMMON or no validated boot image or provisioning file is available.

  • A stack member or supervisor remains missing, version mismatch, or unable to synchronize after storage and image checks.

  • ISSU or xFSU remains active or stalled even after performing the abort procedure.

  • Install state remains inconsistent after the supported commit, abort, rollback, or inactive cleanup proedure.

  • A bootloader, ROMMON, CPLD, or FPGA update fails or is interrupted.

  • An unexpected reload, process crash, watchdog, low-memory event, or forwarding failure occurs.

  • The suggested recovery process requires clearing install state, flash formatting, emergency-install, service internal, or manual changes to package file.

  • The correct rollback point or required package files are absent.

  • The same validated operation fails again after the underlying cause was corrected.
