Chapter 12 Configuring Supervisor Engine Redundancy Using RPR and SSO on Supervisor Engine 7-E, Supervisor
Performing a Software Upgrade
This example shows how to perform a software upgrade:
Switch# config terminal
Switch(config)# config-register 0x2
Switch(config)# boot system flash
bootflash0:cat4500e-universalk9.SSA.03.01.00.150.1.XO.bin
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
Step 3
Switch# config terminal
Switch(config)# config-register 0x2
Switch(config)# boot system flash
device:file_name
Configures the supervisor engines to boot the new image.
If your system was configured to autoboot an earlier
image, issue the following command string to boot the
new image instead:
no boot system flash device:old_file_name
Step 4
Switch(config)# redundancy
Enters redundancy configuration mode.
Step 5
Switch(config-red)# main-cpu
Enters main-cpu configuration submode.
Step 6
Switch(config-r-mc)# auto-syn standard
Synchronizes the configuration elements.
Step 7
Switch(config-r-mc)# end
Returns to privileged EXEC mode.
Step 8
Switch# copy running-config start-config
Saves the configuration.
Step 9
Switch# redundancy reload peer
Reloads the standby supervisor engine and brings it back
online (using the new release of the Cisco IOS-XE
software).
Step 10
Switch# redundancy force-switchover
Conducts a manual switchover to the standby supervisor
engine. The standby supervisor engine becomes the new
active supervisor engine using the new Cisco IOS-XE
software image.
The old active supervisor engine reboots with the new
image and becomes the standby supervisor engine.
