Chapter 5 Configuring RPR and RPR+ Supervisor Engine Redundancy

Performing a Fast Software Upgrade

The fast software upgrade (FSU) procedure supported by RPR allows you to upgrade the Cisco IOS
image on the supervisor engines without reloading the system.

Note

If you are performing a first-time upgrade to RPR from EHSA, you must reload both supervisor engines.
FSU from EHSA is not supported.

To perform an FSU, perform this task:

Command

Purpose

Step 1

Router# copy source_device:source_filename {disk0

| disk1}:target_filename

Copies the new Cisco IOS image to the disk0: device or
the disk1: device on the active supervisor engine.

Or:

Router# copy source_device:source_filename

sup-bootflash:

target_filename

Copies the new Cisco IOS image to the bootflash:
device on the active supervisor engine.

Or:

Router# copy source_device:source_filename

{slavedisk0 | slavedisk1}:target_filename

Copies the new Cisco IOS image to the disk0: device or
the disk1: device on the redundant supervisor engine.

Or:

Router# copy source_device:source_filename

slavesup-bootflash:

target_filename

Copies the new Cisco IOS image to the bootflash:
device on the redundant supervisor engine.

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.
