Displaying ISSU Compatibility Matrix Information
The ISSU compatibility matrix contains information about other software images about 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.
Perform this task to display information about the ISSU compatibility matrix:
