Using upgrade ... all ensures that the primary and standby RPs, as well as the ESPs and SIPs, are updated, which prevents inconsistencies between modules.
The output should now show that the ROMmon version matches the 17.3(1r) release. Troubleshooting
If your compliance requires NIST SP 800-124 (firmware integrity), 173-1r meets the baseline. asr1000-rommon.173-1r.spa.pkg
Look for a line similar to:
Execute the upgrade command pointing to your source package file. This copies the ROMMON code into the hardware's programmable read-only memory components. Using upgrade
If the command fails with an image validation error, the PKG file is likely corrupted. Delete the file, re-download it from Cisco, re-verify the MD5 hash, and try the upgrade again. Router# delete bootflash:asr1000-rommon.173-1r.spa.pkg Use code with caution. Stuck in ROMMON Mode ( rommon 1> )
By carefully following the structured steps and precautions outlined in this guide, you can safely and effectively upgrade your equipment. Always prioritize reading the official Cisco documentation and verifying compatibility before undertaking any critical network infrastructure upgrade.
