Chapter 6 Configuring Supervisor Engine Redundancy on the Catalyst 4507R and 4510R Switches
Copying Files to the Standby Supervisor Engine
This example shows how to perform a software upgrade:
Switch# config terminal
Switch(config)# config-register 0x2
Switch(config)# boot system flash slot0: cat4000-is-mz.121-11b.EW
Switch# copy running-config start-config
Switch# redundancy reload peer
Switch# redundancy force-switchover
Switch#
Copying Files to the Standby Supervisor Engine
If you want to manually copy a file from the active supervisor engine to the slot0: device on the standby
supervisor engine, use this command:
Switch# copy source_device:source_filename slaveslot0:target_filename
To copy a file to the bootflash: device on a standby supervisor engine, use this command:
Switch# copy source_device:source_filename slavebootflash:target_filename
Step 4
Switch# redundancy reload peer
Reloads the standby supervisor engine and bring it back
online (running the new version of the Cisco IOS
software).
Note Before reloading the standby supervisor engine,
make sure you wait long enough to ensure that all
configuration synchronization changes have
completed.
Step 5
Switch# redundancy force-switchover
Conducts a manual switchover to the standby supervisor
engine. The standby supervisor engine becomes the new
active supervisor engine running the new Cisco IOS
software image. The modules reload and the module
software downloads from the new active supervisor
engine.
The old active supervisor engine reboots with the new
image and becomes the standby supervisor engine.
