If you are running a High Availability (HA) pair (two routers or an ASR with dual RPs), ensure both Route Processors are updated. In some cases, you may need to perform the upgrade on the standby RP explicitly or ensure the auto-sync feature is functioning correctly to avoid version mismatches between active and standby supervisors.

Upgrading to 17.3(1r) may cause some modules to enter a "disabled" state.

Upgrading the ROMMON on an ASR 1000 involves downloading the firmware package, verifying its integrity, modifying the boot variables, and executing the upgrade command. Step 1: Download and Verify the Image

Note: Always verify your specific hardware configuration via the show inventory or show platform command before proceeding. Pre-Upgrade Verification Checklist If you are running a High Availability (HA)

Once the system initializes back into the Cisco IOS XE command-line interface, perform a final validation check to ensure everything is operating nominally. Router# show version | include ROMMON Use code with caution.

| Component | Value | Meaning | |-----------|-------|---------| | Platform | asr1000 | Compatible with all ASR 1000 series (1001, 1002, 1004, 1006, 1013, etc.) | | Component | rommon | Indicates this is ROMMON firmware (not IOS-XE, ESP firmware, or SPA drivers) | | Version | 173-1r | Primary firmware revision 173, sub-release 1, with r likely denoting a recommended release or specific build. In Cisco’s scheme, this equates to ROM version 1.73(1r) | | Extension | .spa.pkg | Shared Port Adapter package format – actually a .pkg file containing binary firmware, checksums, and metadata. | Router# copy tftp://192
