Overview

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.

Software Images

 

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:

 

To go back to default mode (RJ45), SFP_MGMT rommon variable has to be unset.

Example:

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.

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:

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

Step 2 Update the upgradeable ROMMON software version:

Step 3 Check the new active ROMMON information:

Step 4 Reload the runtime image on the supervisor engine:

---

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:

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.

Switch 2 Slot 1 Processor Information :

-----------------------------------------------

 

Step 2 Check the active ROMMON information

 

Step 3 Update the upgradeable ROMMON software version:

 

Step 4 Check the new active ROMMON information. It will still point to the old rommonimage

 

Step 5 Do a switchover now.This will reload the present active

Step 6 Repeating step 1 to 4 for SWITCH2 now in steps 5-8 (SW2 is the current ACTIVE).

 

Step 7 Update the upgradeable ROMMON software version

 

Step 8 Check the new active ROMMON information. It will still point to the old rommonimage

 

Step 9 Do a switchover now.This will reload the present active

 

Now, we are back to original scenario:

SW1 became active and SW2 became standby.

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:

Step 2 Disqualify a specific ROMMON region:

Step 3 Reload the supervisor engine for the change to take effect:

Step 4 Verify the change:

 

To select a downloaded ROMMON image, perform this task:

---

Step 1 Check the active ROMMON information:

Step 2 Change the ROMMON preference:

Step 3 Reload the supervisor engine for the change to take effect:

Step 4 Verify the change:

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:

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

Step 2 Update the upgradeable ROMMON software version:

Step 3 Reload the runtime image on the Supervisor box:

Step 4 After the system comes up, Check the new ROMMON information:
