Upgrading the ROMMON and CPLD

This chapter describes the procedures to upgrade the ROMMON on the Cisco ASR 1001-X Router.

This chapter contains the following sections:

Upgrading the ROMMON

The ROMMON must be upgraded on the Cisco ASR 1001-X Router if the system message on the router indicates that the ROMMON requires an upgrade, or when a Cisco technical support representative suggests a ROMMON upgrade.

Checking the Current ROMMON Version

If you are unsure whether a ROMMON upgrade is required, 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 your router. If the output shows that the release to which you plan to upgrade is already installed, you need not upgrade the ROMMON.

For a single form-factor platform such as the Cisco ASR 1001-X Router, all of the following commands display the same output:

  • show rom-monitor 0
  • show rom-monitor F0
  • show rom-monitor FP
  • show rom-monitor R0
  • show rom-monitor RP

In the following example, the output of the show rom-monitor command indicates that an upgrade to Release 15.4(2r)S is not required:

Upgrading the ROMMON for the Cisco ASR 1001-X Router

Use this procedure to upgrade the ROMMON for the Cisco ASR 1001-X Router:

SUMMARY STEPS

  1. (Optional) Run the show platform command or the show rom-monitor slot command to see the current release number of ROMMON on the hardware.
  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 15.4(2r)S, copy the asr1000-rommon.154-2r.S.pkg file.
  3. Run the dir file-system command to verify that the ROMMON file is copied into the specified directory.
  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.
  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.
  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.
  7. Run the enable command at the user prompt to enter the privileged EXEC mode after the boot is complete.
  8. Run the show platform command or the show rom-monitor slot command to verify whether the ROMMON has been upgraded.

DETAILED STEPS

Step 1

(Optional) Run the show platform command or the show rom-monitor slot command to see the current release number of ROMMON on the hardware.

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 15.4(2r)S, copy the asr1000-rommon.154-2r.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.

Note 
If you change the configuration register setting through Cisco IOS after initiating a ROMMON upgrade, but before reloading the router, the configuration register setting will not be applied. Reload the router and allow the ROMMON upgrade to be applied prior to changing the configuration register in Cisco IOS.
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.

Note 
If you enter the reset command twice when booting from the ROMMON prompt, the ROMMON upgrade will automatically fall back to the previous ROMMON image. The following message appears after you enter the reset command the second time, and the earlier version of the ROMMON image is installed: Rommon upgrade requestedMaximum upgrade attempts exceeded, continuing with old Rommon...
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 to verify whether the ROMMON has been upgraded.

Hardware the Require a CPLD Upgrade

The Cisco ASR 1001-X Router has the capability to allow users to perform Complex Programmable Logic Device (CPLD) upgrades in the field.

For details about Cisco ASR 1000 Series Aggregation Services Router hardware configuration combinations that require a CPLD field-programmable upgrade for components, see Upgrading Field Programmable Hardware Devices for Cisco ASR 1000 Series Routers .

Upgrading the CPLD

To upgrade the CPLD, follow these steps:

SUMMARY STEPS

  1. Copy the .pkg file to your bootflash directory.
  2. Execute the upgrade hw-programmable cpld filename bootflash: <cpld.pkg> RP active command:
  3. Press Enter .
  4. To confirm if the upgrade is complete, execute the show platform command:

DETAILED STEPS

Step 1

Copy the .pkg file to your bootflash directory.

Step 2

Execute the upgrade hw-programmable cpld filename bootflash: <cpld.pkg> RP active command:

Router# upgrade hw-programmable cpld filename bootflash:nightster_cpld_14041015.pkg RP active

Upgrade CPLD on Route-Processor 0 from current version 13081317 to 14041015 [Press Enter to confirm]

This command could take up to 10 minutes, please wait and do not power-cycle the chassis or the card. Otherwise, hardware may be unrecoverable. The system will be automatically power-cycled upon completion. [Press Enter to confirm]

Note 
If you decide not to upgrade the CPLD after step 2, press Ctrl-C to abort.
Step 3

Press Enter .

The router upgrades the CPLD, and information will be displayed on the screen. The router then power cycles and returns to your configuration register-based setting (Cisco IOS boot or ROMMON prompt).

Step 4

To confirm if the upgrade is complete, execute the show platform command:

Router# show platform

Checking Hardware and Software Compatibility

Cisco software is packaged in feature sets consisting of software images that support specific platforms. The feature sets that are available for a specific platform depend on which Cisco software images are included in a release. To identify the set of software images available in a specific release or to find out if a feature is available in a given Cisco IOS XE software image, use Cisco Feature Navigator or the corresponding software release notes.

Using Cisco Feature Navigator

Use Cisco Feature Navigator to find information about platform support and software image support. Cisco Feature Navigator enables you to determine which Cisco IOS XE software images support a specific software release, feature set, or platform. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn . An account on Cisco.com is not required.
