Chapter 8 Configuring the Cisco IOS XE In Service Software Upgrade Process
How to Perform the ISSU Process
This example shows how to start the ISSU process, boot the standby supervisor engine in the Standby
Hot state, and load the standby supervisor engine slot (6) with the new IOS XE software image:
Switch> enable
Switch# issu loadversion 5 bootflash:new_image 6 slavebootflash:new_image
%issu loadversion executed successfully, Standby is being reloaded
Switch# show issu state detail
Slot = 5
RP State = Active
ISSU State = Load Version
Operating Mode = Stateful Switchover
Current Image = bootflash:old_image.bin
Pre-ISSU (Original) Image = bootflash:old_image.bin
Post-ISSU (Targeted) Image = bootflash:new_image.bin
Slot = 6
RP State = Standby
ISSU State = Load Version
Operating Mode = Stateful Switchover
Current Image = bootflash:new_image.bin
Pre-ISSU (Original) Image = bootflash:old_image.bin
Post-ISSU (Targeted) Image = bootflash:new_image.bin
Switch# show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 5
Redundancy Mode (Operational) = Stateful Switchover
Redundancy Mode (Configured) = Stateful Switchover
Redundancy State = Stateful Switchover
Manual Swact = enabled
Communications = Up
client count = 81
client_notification_TMR = 240000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 1
keep_alive threshold = 9
RF debug mask = 0
Step 3
Switch# show issu state [detail]
Displays the state of ISSU during the ISSU process. At this
point in the ISSU process, use this command to check that
the standby supervisor engine is loaded and is in SSO mode.
It may take several minutes after entering the
issu loadversion command for Cisco IOS XE software to
load onto the standby supervisor engine and the standby
supervisor engine to transition to SSO mode. If you enter
the show issu state command too quickly, you may not see
the information you need.
Step 4
Switch# show redundancy [states]
Displays redundancy facility state information.
