Upgrade IOS on Redundant SUP 720's

I am not having any luck locating a procedure to upgrade the IOS version on a redundant pair of SUP 720's in a CAT6500 switch. Can someone point me (through the fog of this murky website) to a documented procedure on how to do this? - THANKS IN ADVANCE!

Re: Upgrade IOS on Redundant SUP 720's

Follow the below steps to upgrade the SUP without any downtime.

Step 1

Router# copy source_device:source_filename {disk0 | disk1}:target_filename

Or:

Router# copy source_device:source_filename sup-bootflash:target_filename

Or:

Router# copy source_device:source_filename slavedisk0:target_filename

Or:

Router# copy source_device:source_filename slavesup-bootflash:target_filename

Copies the new Cisco IOS image to bootflash on both supervisor engines.

Step 2

Router# config terminal

Router(config)# config-register 0x2102

Router(config)# boot system flash device:file_name

Configures the supervisor engines to boot the new image.

Step 3

Router# copy running-config start-config

Saves the configuration.

Step 4

Router# hw-module {module num} reset

Reloads the redundant supervisor engine and brings it back online (running the new version of the Cisco IOS software).

Note Before reloading the redundant supervisor engine, make sure you wait long enough to ensure that all configuration synchronization changes have completed.

Step 5

Router# redundancy force-switchover

Conducts a manual switchover to the redundant supervisor engine. The redundant supervisor engine becomes the new active supervisor engine running the new Cisco IOS image. The modules are reloaded and the module software is downloaded from the new active supervisor engine.

The old active supervisor engine reboots with the new image and becomes the redundant supervisor engine.

Note To perform an EHSA to RPR FSU, use the reload command in Step 5.

Router# config terminal

Router(config)# config-register 0x2102

Router(config)# boot system flash disk0:image_name

Router# copy running-config start-config

Router# hw-module reset

Router# redundancy force-switchover

Router#

Copying Files to the Redundant Supervisor Engine

Use the following command to copy a file to the disk0: device on a redundant supervisor engine:

Router# copy source_device:source_filename slavedisk0:target_filename

Use the following command to copy a file to the bootflash: device on a redundant supervisor engine:

Router# copy source_device:source_filename slavesup-bootflash:target_filename

Use the following command to copy a file to the bootflash: device on a redundant MSFC:

Router# copy source_device:source_filename slavebootflash:target_filename

Re: Upgrade IOS on Redundant SUP 720's

Hi,

while the link beneath shows the redundant Sup32 upgrade example, the process with Sup720s is basically the same:

Best regards,
