Displaying Issu Compatibility Matrix Information - Cisco Catalyst 4500 series Administration Manual

Chapter 7 Configuring the Cisco IOS XE In Service Software Upgrade Process
This example shows how to set the rollback timer to 3600 seconds:
Switch> enable
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# issu set rollback-timer 3600
% Rollback timer value set to [ 3600 ] seconds
Switch(config)# exit
Switch# show issu rollback-timer
The Rollback Timer cannot be set in loadversion or runversion state, as the following example illustrates:
Switch# show issu state detail
Switch# show issu rollback-timer
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# issu set rollback-timer 20
% ISSU state should be [ init ] to set the rollback timer

Displaying ISSU Compatibility Matrix Information

The ISSU compatibility matrix contains information about other IOS XE software releases and the
version in question. This compatibility matrix represents the compatibility of the two software versions,
one running on the active and the other on the standby supervisor engine, and the matrix allows the
system to determine the highest operating mode it can achieve. This information helps the user identify
whether to use ISSU.
This task shows how to display information about the ISSU compatibility matrix.
