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

Ensure stable power during the upgrade process. A power failure while flashing ROMMON can corrupt the bootloader and require hardware replacement. Step-by-Step Upgrade Procedure 1. Transfer the Package File

Verify the file integrity by checking the MD5 checksum against Cisco’s documentation: Router# verify /md5 bootflash:asr1000-rommon.173-1r.spa.pkg Use code with caution. Step 3: Executing the Upgrade

Once the router boots back into the Cisco IOS XE operating system, confirm that the update succeeded. Router# show platform | include ROMMON Use code with caution.

When you upgrade IOS-XE on the ASR 1000, the system attempts to upgrade the firmware automatically. You might see logs mentioning FPGA updates.

In some cases, the upgrade process appears to complete successfully, with the router displaying messages like "ROMMON upgrade complete" and verifying the CRC checksum. However, after performing a reload and multiple reboot cycles, the ROM monitor version remains at the older version despite appearing to have been upgraded. asr1000-rommon.173-1r.spa.pkg

The firmware package is the ROM Monitor (ROMMON) image for the Cisco ASR 1000 Series Aggregation Services Routers . It is specifically used to upgrade the low-level boot code on hardware components like Route Processors (RP), Embedded Services Processors (ESP), and line cards (SPA Interface Processors). Why You Need This Upgrade

Router# show version | include ROMMON

If you see "invalid RP package type," the file may be corrupted or you are attempting to use a ROMmon file not suited for your specific RP type (e.g., trying to use an ASR1000-RP2 file on an ASR1001-X) 1.1.1 .

This writes the new ROMMON to the protected ROMMON storage region. Ensure stable power during the upgrade process

Download asr1000-rommon.173-1r.spa.pkg from Cisco Software Download center under "ASR 1000 Series" → "ROMMON Firmware".

Execute the upgrade command pointing to your source package file. This copies the ROMMON code into the hardware's programmable read-only memory components.

ROMMON version: System Bootstrap, Version 17.3(1r), RELEASE SOFTWARE

Once the router boots back into Cisco IOS XE, verify that the new ROMMON version is active: Router# show rom-monitor slot R0 Use code with caution.

The upgrade writes the new image to the clean boot flash region but will not take effect until a hardware reload occurs: Router# reload Use code with caution. 5. Verify the Upgrade

The asr1000-rommon.173-1r.spa.pkg file is designed strictly for specific Route Processors within the ASR 1000 lineup. Do not attempt to load this package onto incompatible hardware, as doing so can cause the system to fail to boot. Supported Route Processors (Fixed configuration router) ASR1002-X (Fixed configuration router) ASR1001-HX and ASR1002-HX ASR1000-RP2 (Modular Route Processor 2) ASR1000-RP3 (Modular Route Processor 3)
