Release Notes for Catalyst 6000 Family and Cisco 7600 Series Internet Router
DFC ROMMON Software


Current Release: 12.1(11r)E2—March 28, 2002
Past Release: 12.1(5r)E1

This publication describes how to upgrade the ROMMON on your Catalyst 6000 family or Cisco 7600 series Internet Router Distributed Forwarding Card (DFC). The ROMMON upgrade is supported on fabric-enabled modules that have the WS-F6K-DFC daughter card.


Tip You should consider the 12.1(11r)E2 ROMMON software upgrade if you need the bug fixes documented in the "Caveats" section.


With this procedure, you can upgrade the ROMMON image similar to the way that you upgrade the Cisco IOS operating system software.

ROMMON software release 12.1(11r)E2 is supported in Catalyst 6000 family and Cisco 7600 series systems that are running Cisco IOS software on the Supervisor Engine 2 and on the MSFC2.

System Software Requirements

The DFC ROMMON software upgrade requires the following system software:

DFC ROMMON software release 12.1(4r)E1 or later on the DFC.

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 DFC ROMMON.

ROMMON Image Overview

The DFC 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

DFC ROMMON software release 12.1(11r)E2 contains bug fixes; no new feature support is added.

Caveats

The following section contains resolved caveat information.

Resolved Caveats in DFC ROMMON Software Release 12.1(11r)E2

This problem could cause a DFC-configured module to not come up on a fully loaded chassis due to a failure to download the image when the EOBC is under stress traffic conditions. This problem is resolved in DFC ROMMON software release 12.1(11r)E2. (CSCdu19133)

Under some circumstances, after doing an online insertion and removal (OIR) or resetting the module with the DFC through the switch console, the DFC might report a Bus Error and fail to boot. This problem is resolved in DFC ROMMON software release 12.1(11r)E2. (CSCdw24401)

The system might fail to recognize the newly installed memory after upgrading the DFC memory to 256 MB using the upgrade kit (MEM-DFC-256MB=). You should upgrade the ROMMON on the DFC to ROMMON software release 12.1(11r)E2. If you are running Cisco IOS Release 12.1(8a)E or later, you can upgrade the ROMMON of the DFC through the software upgrade procedure documented in this publication.

To identify the ROMMON version running on the DFC, enter the remote command module module-no show version command and find the following line in the display output:

System Bootstrap, Version 12.1(4r)E, RELEASE SOFTWARE (fc1) 

In this example, the ROMMON version is 12.1(4r)E.

(CSCdw69150)

Upgrading the DFC ROMMON


Note Before performing this procedure, you must download the new ROMMON image from Cisco.com. The download procedure is the same as downloading Catalyst software images.


To upgrade the ROMMON version on your DFC, perform these steps (in this example, the module with the DFC is in slot 4):


Step 1 Check the active ROMMON information:

Router# show rom-monitor slot 4

   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 DFC (in this example, the image is stored in the route processor bootflash):

Router# upgrade rom-monitor slot 4 file bootflash:c6dfc-rm2.srec.121-11r.E2
Copying bootflash:c6dfc-rm2.srec.121-11r.E2 onto bootflash of dfc#4 CCCCCCCCC
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
Router#
19:40:08: DFC4: ROMMON image upgrade in progress
19:40:08: DFC4: Erasing flash
19:40:11: DFC4: Programming flash
19:40:13: DFC4: Verifying new image
19:40:13: DFC4: ROMMON image upgrade complete
 The card must be reset for this to take effect

Router# 

Step 3 Check the new active ROMMON information:

Router# show rom-monitor slot 4
   Region F1:APPROVED
   Region F2:FIRST_RUN, preferred
   Currently running ROMMON from F1 region 
Router# 

Step 4 Reload the DFC for the change to take effect:

Router# hw-module module 4 reset
Proceed with reload of module? [confirm]
% reset issued for module 4 

<output truncated>

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

Router# show rom-monitor slot 4
   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 procedure in this section is optional and should be used only if you have multiple versions of the upgraded ROMMON image stored on the DFC. These procedures describe how to select a particular ROMMON image for booting and how to disqualify a particular ROMMON region.

Selecting a Stored ROMMON Image on the DFC

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 command 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 DFC, perform these steps:


Step 1 Change the ROMMON preference:

Router# show rom-monitor slot 4
Region F1:FIRST_RUN
Region F2:FIRST_RUN, preferred
Currently running ROMMON from F2 region
Router# upgrade rom-monitor slot 4 preference region1

You are about to mark F1 region of DFC ROMMON in slot 4 as the boot preference region, 
proceed[n]? y
Router#

Step 2 Reload the DFC for the change to take effect:

Router# hw-module module 4 reset
Proceed with reload of module? [confirm]
% reset issued for module 4 

<output truncated>

Step 3 Verify the change:

Router# show rom-monitor slot 4
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 4
Region F1:FIRST_RUN
Region F2:FIRST_RUN, preferred
Currently running ROMMON from F2 region

Router# upgrade rom-monitor slot 4 invalidate region2

You are about to mark F2 region of DFC ROMMON in slot 4 as an invalid region,  
proceed[n]? y
Router#

Step 2 Reload the DFC for the change to take effect:

Router# hw-module module 4 reset
Proceed with reload? [confirm]

<output truncated>

Step 3 Verify the change:

Router# show rom-monitor slot 4
Region F1:FIRST_RUN
Region F2:INVALID
Currently running ROMMON from S (Gold) region
