This example shows how to display stored information regarding the compatibility matrix:

Number of Matrices in Table = 1
Dynamic Image Version Compatibility (DIVC) feature is supported in IOS XE releases. With DIVC, we
store Dynamic(0) rather than Incomp(1), Base(2), or Comp(3), and determine compatibility during
run-time when two different DIVC-capable IOS XE software images are running in the active and
standby supervisor engines during ISSU.
For Catalyst 4500 switches, a value of Dynamic(0) in the stored compatibility-matrix normally results
in Base(2) or Comp(3) upon run-time negotiation between the two IOS XE software images; as of today,
you never observe Incomp(1) as long as the other IOS XE name is present in the stored
compatibility-matrix.
