Chapter 6 Configuring Supervisor Engine Redundancy Using RPR and SSO
Command
Step 9
Switch# redundancy reload peer
Step 10
Switch# redundancy force-switchover
This example shows how to perform a software upgrade:
Switch# config terminal
Switch(config)# config-register 0x2
Switch(config)# boot system flash slot0:cat4000-i5s-mz.122-20.EWA
Switch(config)# redundancy
Switch(config-red)# main-cpu
Switch(config-r-mc)# auto-syn standard
Switch(config-r-mc)# end
Switch# copy running-config start-config
Switch# redundancy reload peer
Switch# redundancy force-switchover
Switch#
This example illustrates how to verify that the running configuration on the active supervisor engine has
successfully synchronized with the redundant supervisor engine:
Switch# config terminal
Switch(config)# redundancy
Switch(config-red)# main-cpu
Switch(config-r-mc)# auto-sync standard
4d01h: %C4K_REDUNDANCY-5-CONFIGSYNC: The bootvar has been successfully synchronized to the
standby supervisor
4d01h: %C4K_REDUNDANCY-5-CONFIGSYNC: The config-reg has been successfully synchronized to
the standby supervisor
4d01h: %C4K_REDUNDANCY-5-CONFIGSYNC: The startup-config has been successfully synchronized
to the standby supervisor
4d01h: %C4K_REDUNDANCY-5-CONFIGSYNC: The private-config has been successfully synchronized
to the standby supervisor
The example above shows that the boot variable, the config-register, and the startup configuration from
the active supervisor engine have successfully synchronized to the redundant supervisor engine.
OL-6696-01
Purpose
Reloads the redundant supervisor engine and brings it
back online (using the new release of the Cisco IOS
software).
Before proceeding to Step 10, ensure that the switch
Note
is operating in RPR mode.
Conducts a manual switchover to the redundant
supervisor engine. The redundant supervisor engine
becomes the new active supervisor engine using the new
Cisco IOS software image.
The old active supervisor engine reboots with the new
image and becomes the redundant supervisor engine.
