Chapter 8 Configuring the Cisco IOS XE In Service Software Upgrade Process
How to Perform the ISSU Process
This example shows how to reset and reload the current standby supervisor engine (slot 1) with the new
Cisco IOS XE software version. After you enter the commitversion command, the standby supervisor
engine boots in the Standby Hot state.
Switch> enable
Switch# issu commitversion 5 slavebootflash:new_image
%issu commitversion executed successfully
Switch# show issu state
Slot = 6
RP State = Active
ISSU State = Init
Slot = 5
RP State = Standby
ISSU State = Init
Use the following to verify that the standby supervisor engine is reloaded with the new software.
Switch# show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 6
Redundancy Mode (Operational) = Stateful Switchover
Redundancy Mode (Configured) = Stateful Switchover
Redundancy State = Stateful Switchover
Manual Swact = enabled
Communications = Up
client count = 88
client_notification_TMR = 240000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 0
keep_alive threshold = 9
RF debug mask = 0
Switch# show redundancy
Redundant System Information :
------------------------------
Available system uptime = 10 hours, 56 minutes
Switchovers system experienced = 1
Standby failures = 1
Last switchover reason = user_forced
Hardware Mode = Duplex
Configured Redundancy Mode = Stateful Switchover
Operating Redundancy Mode = Stateful Switchover
Maintenance Mode = Disabled
Communications = Up
Step 3
Switch# show redundancy [states]
Displays redundancy facility state information.
Step 4
Switch# show issu state [detail]
Displays the state of the during the ISSU process. At this
point in the ISSU process, use this command to check that
the standby supervisor engine is loaded with the new image.
