ASR1000-RP2 and ASR1000-RP3 modules installed in modular chassis (ASR 1004, ASR 1006, ASR 1006-X, ASR 1009-X, and ASR 1013). Step-by-Step Upgrade Guide
In modern IOS-XE releases (like 17.x), ROMMON upgrades are often automatic when using the standard command. The system detects the ROMMON version in the consolidated package and updates it if necessary.
Cisco Bug: CSCwa12192 - ASR1k 17.3(1r) ROMMON upgrade may cause module to go to "disabled" state. Cisco Bug: CSCwa12192. ASR1k 17. ASR1002-X Upgrade version path - Cisco Community
If the upgrade command fails instantly, verify that your active IOS XE release supports the installation command structure. Some older 16.x trains require specific syntax adjustments or upgrade tool patches. asr1000-rommon.173-1r.spa.pkg
Optimizes driver support for modern high-capacity USB drives and updated internal eUSB/SSD solid-state storage modules. Hardware Compatibility
Before proceeding with the ROMMON upgrade, engineers should:
Once the main IOS XE operating system boots up successfully, re-verify your configuration variables using show bootvar and set them correctly using the boot system global configuration command. Cisco Bug: CSCwa12192 - ASR1k 17
Prepares the Route Processor (RP), Embedded Services Processor (ESP), and Shared Port Adapters (SPAs) for operation.
The following procedure outlines how to upgrade the ROMMON on an ASR 1000 series router. 1. Identify Current ROMMON Version
Example: copy tftp: bootflash:asr1000-rommon.173-1r.SPA.pkg . 2. The Upgrade Command ASR1002-X Upgrade version path - Cisco Community If
After the router successfully reboots, verify that the active ROMMON version is indeed running 17.3(1r): Router# show platform Use code with caution. Copied to clipboard
The ROM Monitor (ROMMON) is the bootstrap program that initializes the hardware and boots the Cisco IOS XE operating system on Cisco ASR 1000 Series Aggregation Services Routers. Updating your ROMMON to a stable release like ensures compatibility with modern Cisco IOS XE releases, patches critical hardware vulnerabilities, and resolves system boot bugs.
