Configuring the Cisco IOS XE In Service Software Upgrade Process
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.
