Asr1000-rommon.173-1r.spa.pkg

If your compliance requires NIST SP 800-124 (firmware integrity), 173-1r meets the baseline.

: Upgrading the ROM monitor firmware to support newer IOS XE versions (like 17.3.x through 17.x).

Watch the CLI output. The router will output messages indicating that the upgrade was successful and that the new ROMMON will take effect on the next reload. Step 3: Reload the Router

file to avoid signature mismatch errors that can halt the process

: If the router fails to boot post-upgrade, ensure your configuration register is set to 0x2102 (standard) rather than 0x2100 or 0x0 .

Before diving into the specific file, we need to understand the environment. (ROM Monitor) is a bootstrap firmware that initializes the hardware and loads the operating system. Think of it as the BIOS or UEFI of a computer, but specifically for Cisco networking gear. asr1000-rommon.173-1r.spa.pkg

Upgrading to ROMMON 17.3(1r) may cause some modules to enter a "disabled" state. Stuck Upgrade on RP1:

Before upgrading, check your current ROMMON version:

: Providing a low-level environment to recover from lost passwords, corrupted software images, or hardware failures Separation of Powers If your compliance requires NIST SP 800-124 (firmware

Do not turn off the power during this process. Once the upgrade completes, you must reload the router for the new ROMMON to take effect. reload 5. Verify Successful Upgrade

Log into your router and check the current ROMMON execution version. Router# show platform Use code with caution.
