Chapter 5 Configuring RPR and RPR+ Supervisor Engine Redundancy
Performing a Fast Software Upgrade
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
slot0:target_filename
or:
Router# copy source_device:source_filename
sup-bootflash:target_filename
or:
Router# copy source_device:source_filename
slaveslot0: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 0x2
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
