Upgrading the Supervisor Engine 32 ROMMON Using Catalyst Operating System Software Commands

---

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

---

To upgrade the ROMMON version on a Supervisor Engine 32 running the Catalyst operating system software, perform these steps:

---

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 (where pathname is the location of the image file):

Console> (enable) copy tftp bootdisk

IP address or name of remote host []? 23.255.254.226

Name of file to copy from []? tftpboot/pathname/c6ksup32-rm2.srec.122-18r.SX5

Flash device [bootdisk]? 

Name of file to copy to [c6ksup32-rm2.srec.122-18r.SX5]? 

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

CCCCCCCCCCCC

File has been copied successfully.

Step 3 Program the new ROMMON image to the bootdisk device on the Supervisor Engine 32:

Console> (enable) rommon upgrade bootdisk:c6ksup32-rm2.srec.122-18r.SX5

CCCCCCCCCCCC

ROMMON image upgrade in progress, will take a minute

Erasing flash

Programming flash

ROMMON image upgrade complete, Supervisor must be reset.

---

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 memory is always labeled as the "preferred" image. If you decide that 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.

---

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 32:

Console> (enable) reset

This command will reset the system.

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

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 32. 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 System Software on the Supervisor Engine 32

•Selecting a Stored ROMMON Image on Systems Running Cisco IOS on the Supervisor Engine 32

Selecting a Stored ROMMON Image on Systems Running Catalyst Operating System Software on the Supervisor Engine 32

You can store versions of the ROMMON image in three regions (including the Gold region). 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 that 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 32, follow these steps:

---

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

Selecting a Stored ROMMON Image on Systems Running Cisco IOS on the Supervisor Engine 32

You can store versions of the ROMMON image in three regions (including the Gold region). 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 that 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 32, follow these steps:

---

Step 1 Change the ROMMON preference:

Router# show rom-monitor slot 5 sp

Region F1:FIRST_RUN

Region F2:FIRST_RUN, preferred

Currently running ROMMON from F2 region

Router# upgrade rom-monitor slot 5sp preference region1
