This publication describes how to upgrade the Supervisor Engine 2T and Catalyst 6800 Series Switches ROMMON image. The alternative is to order the upgrade kit and physically replace the ROMMON (boot ROM).
The supervisor engine ROMMON consists of two modules:
A permanent ROMMON software image.
An upgradeable ROMMON software image.

New Features in Catalyst 6840 ROMMON Software Release 15.2(02r)SYS1
SFP Management port support in rommon-The management port (mgmt0) can be operated in the following modes,
– RJ45 (Default mode)
– SFP
The default mode is RJ45.
To enable SFP mode for management port in rommon, SFP_MGMT=1 rommon variable need to be set.
Example:
rommon 1 > SFP_MGMT=1
rommon 2 > sync
rommon 3 >
To go back to default mode (RJ45), SFP_MGMT rommon variable has to be unset.
Example:
rommon 1 > priv
You now have access to the full set of monitor commands.
Warning some commands will allow you to destroy your configuration and/or system images and could render the machine unbootable.
rommon 2 > unset SFP_MGMT
rommon 3 > sync
rommon 4 >

Upgrading the Supervisor Engine 2T ROMMON
Note Recommended procedure for ROMMON upgrade of Supervisor in VSS Quad-Sup SSO (V4SO): Use the command upgrade rom-monitor to upgrade the ROMMON image, preference region/invalidate region on current active Supervisor. Initiate a switchover using the command redundancy force-switchover. Upgrade the current active Supervisor. Four switchovers are required to upgrade all Supervisors. For a VSS, specify the switch number before the slot number keyword, in the commands.
Note ● Before performing this procedure, download the new ROMMON image from www.cisco.com.
In this example, the module is in slot 1.
Step 1 Check the active ROMMON information:
Router# show rom-monitor slot 1 sp Region Gold: version: V12.2(50r)SYS2 Region F1: INVALID, version: NA Region F2: INVALID, version: NA Currently running ROMMON from S (Gold) region Router#
The display indicates that the active ROMMON is running in the gold region.
Step 2 Update the upgradeable ROMMON software version:
Router# upgrade rom-monitor slot 1 sp file tftp://server/tftpboot-users/pyramid_rm2.srec.122-50r.SYS3 Copying tftp://server/tftp-users/pyramid_rm2.srec.122-50r.SYS3 onto SP's bootdisk bootdisk:upg_sp_rommon.srec... Loading tftp-users/pyramid_rm2.srec.122-50r.SYS3 from server (via Vlan69): !!!!!!!!!!!! [OK - 2850876 bytes] timestamp: ROMMON image upgrade in progress timestamp: Signature verification successful timestamp: Erasing flash timestamp: Programming flash timestamp: Verifying new image timestamp: ROMMON image upgrade complete, Supervisor engine must be reloaded. Router#
Step 3 Check the new active ROMMON information:
Router# show rom-monitor slot 1 sp Region Gold: version: V12.2(50r)SYS2 Region F1: APPROVED, version: V12.2(50r)SYS3, preferred Region F2: INVALID, version: NA Currently running ROMMON from S (Gold) region Router#
Step 4 Reload the runtime image on the supervisor engine:
Router# reload Proceed with reload? [confirm]
Note ● Be sure to complete Step 5 before performing either or the following actions:
An online insertion and removal (OIR) of the supervisor engine.
Power cycling the supervisor engine. 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 Gold: version: V12.2(50r)SYS2 Region F1: APPROVED, version: V12.2(50r)SYS3, preferred Region F2: INVALID, version: NA Currently running ROMMON from F1 region Router#
The “Region F1” field should show “APPROVED” and “preferred.” The ROMMON stored in the Region F1 is now the active ROMMON.
Upgrading ROMMON For a Supervisor Engine 2T VSS
This example is based on a QUAD SUP VSS (2 SUPs in each chassis- SW1 and SW2).
Same procedure applies to a DUAL SUP VSS (1 SUP in each chassis- SW1 and SW2)
Step 1 Check the slot of the SUP in both chassis, using show switch virtual redundancy command or a show mod sw 1 or show mod sw 2 commands.
QUADSUP_VSS_TEST#sh sw virtual
Switch mode : Virtual Switch
Virtual switch domain number : 100
Local switch number : 1
Local switch operational role: Virtual Switch Active
Peer switch number : 2
Peer switch operational role : Virtual Switch Standby
QUADSUP_VSS_TEST#sh sw virtual redundancy
My Switch Id = 1
Peer Switch Id = 2
Last switchover reason = user forced
Configured Redundancy Mode = sso
Operating Redundancy Mode = sso
Switch 1 Slot 1 Processor Information :
-----------------------------------------------
Current Software state = ACTIVE
Uptime in current state = 8 minutes
Image Version = Cisco IOS Software, s2t54 Software (s2t54-IPSERVICESK9-M), Version 15.2(1)SY2, RELEASE SOFTWARE (fc3)
Step 9 Do a switchover now.This will reload the present active
QUADSUP_VSS_TEST#redundancy force-switchover
This will reload the active unit and force switchover to standby[confirm]
Preparing for switchover.
Now, we are back to original scenario:
SW1 became active and SW2 became standby.
QUADSUP_VSS_TEST#sh sw virtual
Switch mode : Virtual Switch
Virtual switch domain number : 100
Local switch number : 1
Local switch operational role: Virtual Switch Active
Peer switch number : 2
Peer switch operational role : Virtual Switch Standby
After this, check the "show version" output to see the new ROMMON. It should point to 12.2(50r)SYS3.
Step 10 (Optional) After Step 3, go to Step 5, upgrade the standby rommon and reload the full chassis (VSS) using the QUADSUP_VSS_TEST#redundancy reload shelf command.
Selecting a ROMMON Image
There are three regions (including the Gold region) where versions of the ROMMON image can reside.
The ROMMON software upgrade feature supports two ROMMON images (one in region F1, the second in region F2) in addition to the ROMMON version in the gold region. You can change the preference as required. The change takes effect after a reset.
To disqualify a region with a downloaded ROMMON version and use the ROMMON version in the gold region, perform these steps:
Step 1 Check the active ROMMON information:
Router# show rom-monitor slot 1 sp Region Gold: version: V12.2(50r)SYS2 Region F1:APPROVED, version: V12.2(50r)SYS3, preferred Region F2:INVALID, version: NA Currently running ROMMON from F1 region
You are about to mark F1 region of SP ROMMON in slot 1 as an invalid region, proceed[n]? y Router#
Step 3 Reload the supervisor engine for the change to take effect:
Router# reload Proceed with reload? [confirm]
<output truncated>
Step 4 Verify the change:
Router# show rom-monitor slot 1 sp Region Gold: version: V12.2(50r)SYS2 Region F1:INVALID, version: V12.2(50r)SYS3 Region F2:INVALID, version: NA Currently running ROMMON from S (Gold) region
To select a downloaded ROMMON image, perform this task:
Step 1 Check the active ROMMON information:
Router# show rom-monitor slot 1 sp Region Gold: version: V12.2(50r)SYS2 Region F1:APPROVED, version: V12.2(50r)SYS3 Region F2:INVALID, version: NA Currently running ROMMON from S (Gold) region
You are about to mark F1 region of SP ROMMON in slot 5 as the boot preference region, proceed[n]? y Router#
Step 3 Reload the supervisor engine for the change to take effect:
Router# reload Proceed with reload? [confirm]
<output truncated>
Step 4 Verify the change:
Router# show rom-monitor slot 1 sp Region Gold: version: V12.2(50r)SYS2 Region F1:APPROVED, version: V12.2(50r)SYS3, preferred Region F2:INVALID, version: NA Currently running ROMMON from F1 region
Upgrading the Catalyst 6800 Series Switches ROMMON
Note Recommended procedure for ROMMON upgrade of Catalyst 6800 series switches in VSS is by using the command upgrade rom-monitor.
Note Before performing this procedure, download the new ROMMON image from www.cisco.com.
In this example, the module is in slot 1.
Step 1 Check the active ROMMON information:
Router#sh rom-monitor slot 1 sp
Rommon image is running from UPGRADABLE region

Router#
The display indicates that the active ROMMON is running in the UPGRADABLE region.
Step 2 Update the upgradeable ROMMON software version:
ROMMON image upgrade complete, Supervisor engine must be reloaded.
Router#
Step 3 Reload the runtime image on the Supervisor box:
Router#reload
Proceed with reload? [confirm]
Step 4 After the system comes up, Check the new ROMMON information:
Router# show rom-monitor slot 1 sp
Rommon image is running from UPGRADABLE region
