Chapter 6 Configuring Supervisor Engine Redundancy on the Catalyst 4507R and 4510R Switches

Performing a Software Upgrade

This example shows how to disable default automatic synchronization and allow only automatic synchronization of the config-registers of the active supervisor engine to the standby supervisor engine, while disallowing synchronization of the startup configuration:

Switch(config)# redundancy

Switch(config-red)# main-cpu

Switch(config-r-mc)# no auto-sync standard

Switch(config-r-mc)#auto-sync config-register

Switch(config-r-mc)# end

Performing a Software Upgrade

The software upgrade procedure supported by supervisor engine redundancy allows you to upgrade the Cisco IOS software image on the supervisor engines without reloading the system.

To perform a software upgrade, perform this task:

	Command	Purpose
Step 1	Switch# copy source_device:source_filename	Copies the new Cisco IOS software image to bootflash on
	slot0:target_filename	both supervisor engines.
	Or:
	Switch# copy source_device:source_filename
	bootflash:target_filename
	Or:
	Switch# copy source_device:source_filename
	slaveslot0:target_filename
	Or:
	Switch# copy source_device:source_filename
	slavebootflash:target_filename
Step 2
	Switch# config terminal	Configures the supervisor engines to boot the new image.
	Switch(config)# config-register 0x2
	Switch(config)# boot system flash
	device:file_name
Step 3
	Switch# copy running-config start-config	Saves the configuration.
