Loading New Cisco IOS Software on the New Standby Supervisor Engine
This task explains how to load new version of Cisco IOS software to the new standby supervisor engine.
Perform this task at the active supervisor engine:
This example shows how to reset and reload the current standby supervisor engine (slot 1) with the new
Cisco IOS software version. After entering the commitversion command, the standby supervisor engine
boots in the Standby Hot state.
Switch> enable
Switch# issu commitversion 1 slavebootflash:new_image
Wait till standby supervisor is reloaded with the new image. Then apply the following:
Switch# show redundancy states
00:17:12: %RF-5-RF_TERMINAL_STATE: Terminal state reached for (SSO)
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Secondary
Unit ID = 2
Redundancy Mode (Operational) = Stateful Switchover
Redundancy Mode (Configured) = Stateful Switchover
Redundancy State = Stateful Switchover
Maintenance Mode = Disabled
Manual Swact = enabled
Communications = Up
client count = 39
client_notification_TMR = 240000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 0
keep_alive threshold = 18
RF debug mask = 0x0
