ROMmon Overview

The ROMmon must be upgraded on an Cisco ASR 1000 Series Router that requires a ROMmon upgrade. An upgrade to this image is necessary only if a system message on the router indicates that the ROMmon on the router requires an upgrade, or a Cisco technical support representative suggests a ROMmon upgrade.

The ROMmon can be upgraded on any of the following hardware components on a Cisco ASR 1000 Series Router:

•Integrated RP1, field-replaceable ESP, and integrated SIP10 on the Cisco ASR 1002 Router (Cisco ASR1002)

•Integrated RP1, ESP, and SIP10 on Cisco ASR 1002-Fixed Router (Cisco ASR 1002-F)

•Cisco ASR 1000 Series Route Processor 1 (Cisco ASR1000-RP1)

•Cisco ASR 1000 Series Route Processor 2 (Cisco ASR1000-RP2)

•5-Gbps Cisco ASR 1000 Series ESP (Cisco ASR1000-ESP5)

•10-Gbps Cisco ASR 1000 Series ESP (Cisco ASR1000-ESP10)

•Cisco ASR 1000 Embedded Services Processor 10G Non Crypto Capable (Cisco ASR1000-ESP10-N)

•20-Gbps Cisco ASR 1000 Series ESP (Cisco ASR1000-ESP20)

•Cisco ASR 1000 Series SPA Interface Processor (SIP)10 (Cisco ASR1000-SIP10)

•Cisco ASR 1000 Series SPA Interface Processor (SIP)40 (Cisco ASR1000-SIP40)

•40-Gbps Cisco ASR 1000 Series ESP (Cisco ASR1000-ESP40)

The ROMmon software for RPs, ESPs, and SIPs can be upgraded collectively or individually.

Compatibility Requirements

The following are the compatibility requirements for upgrading the ROMmon image:

•You must have access to the privileged EXEC mode prompt or the diagnostic mode prompt on the router.

•All the system components must be running Cisco IOS XE Release 2.4.0 or a later release before you perform the upgrade.

•After you upgrade a system component to the current ROMmon release, you cannot run any Cisco IOS XE release earlier than Cisco IOS XE Release 2.4.0.

•A downgrade to a supported ROMmon release converts the ROMVAR table to the appropriate smaller size.

ROMmon Release 12.2(33r)XN1, ROMmon Release 12.2(33r)XN2, ROMmon Release 12.2(33r)XNB, ROMmon Release 12.2(33r)XNC, and ROMmon Release 12.2(33r)XND1 are all supported for downgrade from ROMmon Release 15.0(1r)S. Similarly, ROMmon Release 12.2(33r)XN1, ROMmon Release 12.2(33r)XN2, ROMmon Release 12.2(33r)XNB, ROMmon Release 12.2(33r)XNC, ROMmon Release 12.2(33r)XND1, and ROMmon Release15.0(1r)S are all supported for downgrade from ROMmon Release 15.2(1r)S.

Note During the downgrade process, if it is found that the existing ROMVAR table is too large to fit into the smaller table used in the target ROMmon release (that is, the earlier ROMmon release), the downgrade stops and an error message is displayed. This error message instructs you to drop the system to the ROMmon prompt and clear some of the variable settings. Follow these instructions, and then retry the downgrade.

Note If you require a FIPS 140-2-compliant environment, ROMmon Version 12.2(33r)XND1 is a required update. Cisco IOS XE Release 3.1.0S and ROMmon Release 15.0(1r)S are currently not FIPS certified. Similarly, Cisco IOS XE Release 3.4.0S and ROMmon Release 15.2(1r)S are currently not FIPS certified.

Upgrading the ROMmon

This section covers the following topics:

•Checking the Current ROMmon Version

•Upgrading the ROMmon for All the RPs, ESPs, and SIPs on a Router

•Upgrading the ROMmon for a Single RP, ESP, or SIP on a Router

Checking the Current ROMmon Version

If you are unsure whether a ROMmon upgrade is required or if you have installed a new RP, ESP, or SIP that requires an upgrade, follow the instructions provided in this section.

Run the show rom-monitor command or the show platform command to display the version of ROMmon running on any RP, ESP, or SIP in your router. If the output shows that the release to which you plan to upgrade is already installed, you need not upgrade the ROMmon. In the following example, the output of the show rom-monitor command indicates that an upgrade to Release 15.2(1r)S is not required: 

Router# show rom-monitor r0

System Bootstrap, Version 15.2(1r)S, RELEASE SOFTWARE (fc1)

Technical Support: http://www.cisco.com/techsupport

Copyright (c) 2011 by cisco Systems, Inc.

If the output of the command indicates an earlier ROMmon version or a system message indicates that one of the ROMmon installations on the Cisco ASR 1000 Series Routers needs an upgrade, a ROMmon upgrade may benefit the corresponding RP, ESP, or SIP. In the following example, the output of the show platform command shows that an earlier ROMmon version is currently installed. In this scenario, you can upgrade to Release 15.2(1r)S.

Upgrading the ROMmon for All the RPs, ESPs, and SIPs on a Router

Use this procedure to upgrade the ROMmon for all the RPs, ESPs, and SIPS on a router:

Note Ensure that all the system components are running Cisco IOS XE Release 2.4.0 or a later release before you perform the procedure.

Step 1 (Optional) Run the show platform command or the show rom-monitor slot command for each RP, ESP, and SIP in the router to see the current release numbers of ROMmon on the hardware. See the "Checking the Current ROMmon Version" section for information about interpreting the output of the command that you run.

Step 2 If the ROMmon image has not been copied onto the router, copy the PKG file that is made available as part of this ROMmon release onto the bootflash: or usb[0-1]: file system using the copy source-location destination-location command. For example, if you are upgrading to Release 15.2(1r)S, copy the asr1000-rommon.152-1r.S.pkg file.

Step 3 Run the dir file-system command to verify that the ROMmon file is copied into the specified directory.

Step 4 Run the upgrade rom-monitor filename location all command to begin the ROMmon image upgrade, where location is the path to the ROMmon file.

Caution Do not remove hardware, turn off power, or interrupt the router in any way during the ROMmon upgrade. Although the router should be able to recover from most interruptions during the ROMmon upgrade, certain scenarios may cause unpredictable problems.

Step 5 Messages pertaining to the upgrade are displayed on the console. After the display of these messages stops and the router prompt is available, run the reload command to reload the router.

Step 6 If autoboot has not been enabled by using the config-register 0x2102 command, run the boot filesystem:/file-location command at the ROMmon prompt to boot the Cisco IOS XE image, where filesystem:/file-location is the path to the consolidated package file. The ROMmon upgrade is not permanent for any piece of hardware until the Cisco IOS XE image is booted.

Step 7 Run the enable command at the user prompt to enter the privileged EXEC mode after the boot is complete.

Step 8 Run the show platform command or the show rom-monitor slot command for each RP, ESP, and SIPin the router to verify whether the ROMmon has been upgraded.

Example of Upgrading the ROMmon for All the RPs, ESPs, and SIPs on a Router

The following sequence of commands is an example of the procedure to upgrade the ROMmon for all the RPs, ESPs, and SIPs on a router:

Upgrading the ROMmon for a Single RP, ESP, or SIP on a Router

Use this procedure to upgrade the ROMmon for a single RP, ESP, or SIP on a Cisco ASR 1000 Series Router:

Note Ensure that all the system components are running Cisco IOS XE Release 2.4.0 or a later release before you perform the procedure.

Step 1 (Optional) Run the show platform command or the show rom-monitor slot command for each RP, ESP, and SIP in the router to see the current release numbers of ROMmon on the hardware. See the "Checking the Current ROMmon Version" section for information about interpreting the output of the command that you run.

Step 2 If the ROMmon image has not been copied onto the router, copy the PKG file that is made available as part of this ROMmon release onto the bootflash: or usb[0-1]: file system using the copy source-location destination-location command. For example, if you are upgrading to Release 15.2(1r)S, copy the asr1000-rommon.152-1r.S.pkg file.

Step 3 Run the dir file-system command to verify whether the ROMmon file is copied into the specified directory.

Step 4 Run the upgrade rom-monitor filename location slot command to begin the ROMmon image upgrade, where location is the path to the ROMmon file and slot specifies the hardware that will receive the ROMmon upgrade.

Caution Do not remove hardware, turn off power, or interrupt the router in any way during the ROMmon upgrade. Although the router should be able to recover from most interruptions during the ROMmon upgrade, certain scenarios may cause unpredictable problems.

Step 5 Messages pertaining to the upgrade are displayed on the console. After the display of these messages stops and the router prompt is available, run the hw-module slot slot reload command to reload the hardware that was upgraded.

Note The hw-module slot slot reload command cannot be used to reload an active RP. If you must reload an active RP to complete a ROMmon upgrade, reload the RP using one of the following methods:
- Run the reload command to reload the entire router.
- Force a switchover using the redundancy force-switchover command, and then run the hw-module slot slot reload command on the RP after it has become the standby RP.

Note The ROMmon upgrade is not permanent for any piece of hardware until a Cisco IOS XE Release 12.2(33r)XND1 or newer image is booted. If ROMmon is configured to manually boot on your system, run the boot command to boot the Cisco IOS XE image and make the upgrade permanent.

Step 6 Run the show platform command or the show rom-monitor slot command for each RP, ESP, and SIP in the router to confirm that the ROMmon has been upgraded.
