Chapter 5 Configuring Virtual Switching Systems
In-Service Software Upgrade (ISSU) on a VSS
This example shows how to set the rollback timer to 3600 seconds:
Switch> enable
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# issu set rollback-timer 3600
% Rollback timer value set to [ 3600 ] seconds
Switch(config)# exit
Switch# show issu rollback-timer
Rollback Process State = Not in progress
Configured Rollback Time = 60:00
The Rollback Timer cannot be set in loadversion or runversion state, as the following example illustrates:
Switch# show issu state detail
Slot = 1
RP State = Active
ISSU State = Load Version
Operating Mode = Stateful Switchover
Current Image = bootflash:old_image
Pre-ISSU (Original) Image = bootflash:old_image
Post-ISSU (Targeted) Image = bootflash:new_image
Slot = 11
RP State = Standby
ISSU State = Load Version
Operating Mode = Stateful Switchover
Current Image = bootflash:new_image
Pre-ISSU (Original) Image = bootflash:old_image
Post-ISSU (Targeted) Image = bootflash:new_image
Switch# show issu rollback-timer
Rollback Process State = Not in progress
Configured Rollback Time = 60:00
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# issu set rollback-timer 20
% ISSU state should be [ init ] to set the rollback timer
The ISSU Compatibility Matrix
The ISSU Compatibility Matrix contains information about the compatibility of the IOS XE software
version currently running on the system, and other versions. The Compatibility Matrix deals with two
kinds of information:
• Stored Information, page 5-83
• Negotiated Information, page 5-83
Step 4
Switch(config)# exit
Returns the user to privileged EXEC mode.
Step 5
Switch# show issu rollback-timer
Displays the current setting of the ISSU rollback timer.
