Always save your configuration: copy running-config startup-config 4. How to Upgrade ROMMON (17.3(1r))
Execute the upgrade command pointing to your source package file. This copies the ROMMON code into the hardware's programmable read-only memory components.
| Platform | Applicable | Notes | |----------|------------|-------| | ASR 1001 | Yes | Integrated RP/ESP | | ASR 1001-X | Yes | Common bootflash issues resolved | | ASR 1002-X | Yes | Widely deployed – highly recommended upgrade | | ASR 1004 | Yes | Most benefits for dual-ESP setups | | ASR 1006 | Yes | Chassis with redundant RPs | | ASR 1013 | Yes | High-end chassis – critical for large bootflash | | ASR 1002-HX / 1006-HX | Partial | Newer generation uses different ROMMON branch, but this file works as fallback | asr1000-rommon.173-1r.spa.pkg
Once the operating system loads, re-verify your boot system variables using show bootvar and set them correctly in the configuration mode. Dual RP Out-of-Sync Errors
The output should clearly reflect as the active ROMMON version for your running slot(s). Troubleshooting and Technical Tips
Are you upgrading this as part of a larger , or just a standalone firmware patch ? : The central data plane engine
ROMMON packages are relatively compact, but clogged bootflash directories containing old core dumps or system logs can block transfers. Free up space using the delete bootflash:filename command followed by squeeze bootflash: if required by your filesystem structure.
The package belongs to the 17.3 release train of Cisco hardware diagnostics and initialization software. Upgrading to this specific version introduces several critical infrastructure benefits:
The upgrade is until the hardware is reloaded. This copies the ROMMON code into the hardware's
The asr1000-rommon.173-1r.spa.pkg file represents a critical milestone in the Cisco ASR 1000 series router firmware evolution, particularly for organizations upgrading to IOS XE 17.x releases and beyond. While the upgrade provides important stability improvements and vulnerability fixes, the irreversible nature of this ROMMON version demands careful planning and pre-upgrade verification.
One common point of confusion for administrators is the difference between ROMMON and FPGA updates.
