Release Notes for Catalyst 6000 Family and Cisco 7600 Series Internet Router Supervisor Engine 2 ROMMON

Current Release: 7.1(1)—December 28, 2001
Past Releases: 6.1(4)

This publication describes how to determine if you need to upgrade the ROMMON on your
Catalyst 6000 family or Cisco 7600 series Internet Router Supervisor Engine 2 (WS-X6K-S2-MSFC2, WS-X6K-S2U-MSFC2) and also provides the procedure to download the new ROMMON image from Cisco.com and then upgrade the ROMMON on your Supervisor Engine 2.

With this procedure, you can upgrade the ROMMON image similar to the way that you upgrade the operating system software (supervisor engine software or MSFC Cisco IOS software). Without this procedure, you have to order the upgrade kit and physically replace the ROMMON (boot ROM).

Note The ROMMON software upgrade procedure in this publication applies only to Supervisor Engine 2 with ROMMON software release 6.1(3) or later. If your ROMMON is not software release 6.1(3) or later, refer to the Catalyst 6000 Family Supervisor Engine 2 Boot ROM and Bootflash Device Upgrade Installation Note for information on upgrading your ROMMON (Boot ROM) hardware to software release 6.1(3).

ROMMON Image Overview

The Supervisor Engine 2 ROMMON consists of two modules:

•A resident module that is not changed during the upgrade procedure.

•An upgradable module that is updated during the upgrade procedure. This is the only module that you will download from Cisco.com.

New and Changed Information

Supervisor Engine 2 ROMMON software release 7.1(1) introduces support for the MEM-C6K-ATA-1-64M= (64MB) PCMCIA ATA FlashDisk device.

The following guidelines apply to the PCMCIA ATA FlashDisk device:

•After a reset, ROMMON release 7.1(1) implements a delay of 200 micro seconds (ms) before you can access the PCMCIA ATA FlashDisk device.

•The Read/Write access time for the PCMCIA ATA FlashDisk device is 150 nano second (ns), and the Read/Write cycle time is 280 ns.

•ROMMON release 7.1(1) allows a maximum of 300 ns for each of these parameters.

Note Support for the PCMCIA ATA FlashDisk is for Catalyst 6000 family and Cisco 7600 series systems that are running Cisco IOS Release 12.1(8a)EX or 12.1(11b)E and later on the Supervisor Engine 2 and on the MSFC2. Support for the PCMCIA ATA FlashDisk in systems running Cisco IOS on the MSFC and Catalyst operating software on the supervisor engine requires Catalyst software release 7.5(1) or later releases.

Note In a system running Cisco IOS on both the MSFC and the supervisor engine, disk0: refers to the PCMCIA device. In a system running Cisco IOS on the MSFC and Catalyst operating software on the supervisor engine, slot0: refers to the PCMCIA device (with the exception of the ATA FlashDisk, which is accessed using disk0:).

Upgrading the Supervisor Engine 2 ROMMON Using Catalyst Operating Software Commands

To upgrade the ROMMON version on a Supervisor Engine 2 running Catalyst operating software, perform these steps:

Note Before performing this procedure, you need to download the new ROMMON image from Cisco.com. The download procedure is the same as downloading supervisor engine software images.

Step 1 Check the active ROMMON information: 

Console> (enable) rommon show


Region F1: INVALID

Region F2: INVALID

Currently running ROMMON from S (Gold) region

The display indicates that the active ROMMON is running in the "Gold" region.

Step 2 Download the new ROMMON image from the TFTP server: 

Console> (enable) copy tftp flash

IP address or name of remote host []? 23.255.254.226

Name of file to copy from []? tftpboot/rommon/cat6000-SUP2-rm2.6-1-4.srec

Flash device [bootflash]? bootflash

Name of file to copy to [cat6000-SUP2-rm2.6-1-4.srec]? 


25081216 bytes available on device bootflash, proceed (y/n) [n]? y

CCCCCCCCCCCC

File has been copied successfully.

Step 3 Program the new ROMMON image to the bootflash device on the Supervisor Engine 2:

Note The software automatically stores the specified image to a region other than the region that accepted the last upgraded image. For example, if the last upgrade command put the image in
Region F1, the current upgrade command will store the image in Region F2 and set it as the "preferred" region when the next system reset occurs. If the last upgrade command stored the image to Region F2, the current upgrade command will store the image to Region F1.

The image that is most recently stored into the Flash is always labeled as the "preferred" image. If you decide you do not want this upgrade image, you can switch to the other region or the Gold region using the rommon prefer or rommon invalidate commands. 

Console> (enable) rommon upgrade bootflash:cat6000-SUP2-rm2.6-1-4.srec

CCCCCCCCCCCC

ROMMON image upgrade in progress, will take a minute

Erasing flash

Programming flash

ROMMON image upgrade complete, Supervisor must be reset.

Step 4 Check the new active ROMMON information: 

Console> (enable) rommon show


Region F1: FIRST_RUN, preferred

Region F2: INVALID

Currently running ROMMON from S (Gold) region

The "Region F1" field should show "FIRST_RUN, preferred."

Step 5 Reset the Supervisor Engine 2: 

Console> (enable) reset

This command will reset the system.

Do you want to continue (y/n) [n]? y

Upgrading the Supervisor Engine 2 ROMMON Using Cisco IOS Commands

Note For Catalyst 6000 family and Cisco 7600 series systems running Cisco IOS software on the Supervisor Engine 2 and on the MSFC2, Cisco IOS Release 12.1(8a)EX is the first software release that supports a software upgrade of the ROMMON version.

To upgrade the ROMMON version on your Supervisor Engine 2 using Cisco IOS commands, perform these steps:

Note Before performing this procedure you need to download the new ROMMON image from Cisco.com. The download procedure is the same as downloading supervisor engine software images.

Step 1 Check the active ROMMON information: 

Router# show rom-monitor slot 1 sp


   Region F1:APPROVED, preferred

   Region F2:INVALID

   Currently running ROMMON from F1 region 

Router#

The display indicates that the active ROMMON is running in region1.

Step 2 Program the new ROMMON image to the Flash device on the Supervisor Engine 2: 

Router# upgrade rom-monitor slot 1 sp file tftp://dirt/tftpboot-users/A2_71059.srec


   ROMMON image upgrade in progress

   Erasing flash

   Region F1:APPROVED

   Region F2:FIRST_RUN, preferred

   Currently running ROMMON from F1 region 

Router#

Step 4 Reload the runtime image on the Supervisor Engine 2: 

Router# reload 

Proceed with reload? [confirm]

Caution Be sure to complete Step 5 before performing an online insertion and removal (OIR) of the Supervisor Engine 2 or power cycling the Supervisor Engine 2. The ROMMON upgrade might fail if you perform either of these actions before verifying that the runtime image successfully booted.

Step 5 After the system comes up, check the ROMMON information again: 

Router# show rom-monitor slot 1 sp

   Region F1:APPROVED

   Region F2:APPROVED, preferred

   Currently running ROMMON from F2 region 

Router#

The "Region2" field should show "APPROVED, preferred." The ROMMON stored in the Region2 is now the active ROMMON.

Storing More Than One ROMMON Image

The procedures in this section are optional and should be used only if you have multiple versions of the upgraded ROMMON image stored on the Supervisor Engine 2. These procedures describe how to select a particular ROMMON image for booting and how to disqualify a particular ROMMON region.

These sections show how to select a stored ROMMON image for booting:

•Selecting a Stored ROMMON image on Systems Running Catalyst Operating Software on the Supervisor Engine 2

•Selecting a Stored ROMMON Image on Systems Running Cisco IOS on the Supervisor Engine 2

Selecting a Stored ROMMON image on Systems Running Catalyst Operating Software on the Supervisor Engine 2

There are three regions (including the Gold region) where versions of the ROMMON image can be stored. You can use the rommon prefer and rommon invalidate commands to switch between regions.

The ROMMON software upgrade feature allows you to have two upgraded ROMMON images (one in region F1, the second in region F2) in addition to the "Gold" ROMMON stored on the one-time programmable (OTP) EPROM section of the ROMMON. Use the rommon preference command to select which ROMMON will be the preferred ROMMON the next time the system is booted. You can change the preference as often as you like. The changes do not take effect until you reset the system.

To select a particular ROMMON image stored on the Supervisor Engine 2, perform this task:

Step 1 Change the ROMMON preference. 

Console> (enable) rommon prefer F2


ROMMON in region F2 now has the highest boot preference.

Supervisor must be reset for this to take effect.

Console> (enable) rommon show


Region F1: FIRST_RUN

Region F2: FIRST_RUN, preferred

Currently running ROMMON from F1 region


Console> (enable) rommon prefer F1


ROMMON in region F1 now has the highest boot preference.

Supervisor must be reset for this to take effect.

Console> (enable) rommon show


Region F1: FIRST_RUN, preferred

Region F2: FIRST_RUN

Currently running ROMMON from F1 region

Step 2 You can also disqualify a specific region of ROMMON and use the other region or go back to using the "Gold" ROMMON stored in the OTP EPROM section by using the rommon invalidate command.

To disqualify a specific ROMMON region, enter these commands: 

Console> (enable) rommon invalidate F1

Do you want to mark F1 region INVALID [n]?y


done!

Supervisor must be reset for this to take effect.

Console> (enable) rommon invalidate F2

Do you want to mark F2 region INVALID [n]?y


done!

Supervisor must be reset for this to take effect.

Console> (enable) rommon show


Region F1: INVALID

Region F2: INVALID

Currently running ROMMON from F1 region


Console> (enable) reset

This command will reset the system.

Do you want to continue (y/n) [n]? y

The display indicates that the active ROMMON is running in the "Gold" region.

Selecting a Stored ROMMON Image on Systems Running Cisco IOS on the Supervisor Engine 2

There are three regions (including the Gold region) where versions of the ROMMON image can be stored. You can use the upgrade rom-monitor slot preference and upgrade rom-monitor slot preference commands to switch between regions.

The ROMMON software upgrade feature allows you to have two upgraded ROMMON images (one in region F1, the second in region F2) in addition to the "Gold" ROMMON stored on the one-time programmable (OTP) EPROM section of the ROMMON. Use the upgrade rom-monitor slot preference command to select which ROMMON will be the preferred ROMMON the next time the system is booted. You can change the preference as often as you like. The changes do not take effect until you reset the system.

To select a particular ROMMON image stored on the Supervisor Engine 2, perform this task:

Step 1 Change the ROMMON preference: 

Router# show rom-monitor slot 1 sp

Region F1:FIRST_RUN

Region F2:FIRST_RUN, preferred

Currently running ROMMON from F2 region

Router# upgrade rom-monitor slot 1 sp preference region1


You are about to mark F1 region of SP ROMMON in slot 1 as the boot preference region,

proceed[n]? y

Router#

Step 2 Reload the Supervisor Engine for the change to take effect: 

Router# reload

Proceed with reload? [confirm]


<output truncated>

Step 3 Verify the change: 

Router# show rom-monitor slot 1 sp

Region F1:APPROVED, preferred

Region F2:APPROVED

Currently running ROMMON from F1 region

You can also disqualify a specific region of ROMMON and use the other region or go back to using the "Gold" ROMMON stored in the OTP EPROM section by using the upgrade rom-monitor slot invalidate command.

To disqualify a specific ROMMON region, perform these steps:

Step 1 Disqualify a specific ROMMON region: 

Router# show rom-monitor slot 1 sp

Region F1:FIRST_RUN

Region F2:FIRST_RUN, preferred

Currently running ROMMON from F2 region


Router# upgrade rom-monitor slot 1 sp invalidate region2


You are about to mark F2 region of SP ROMMON in slot 1 as an invalid region,

proceed[n]? y

Router#

Step 2 Reload the Supervisor Engine for the change to take effect: 

Router# reload

Proceed with reload? [confirm]


<output truncated>

Step 3 Verify the change: 

Router# show rom-monitor slot 1 sp

Region F1:FIRST_RUN

Region F2:INVALID

Currently running ROMMON from S (Gold) region
