 Use the SHOW LICENSE BRIEF command in the Privileged Exec
mode to confirm that you installed the VCStack Plus licenses and
enabled the feature on the switches. If a switch does not have the
license, perform “Activating the VCStack Plus Feature License” on
page 291 to install it. If the command shows that the license is
activated but the feature is not enabled, perform “Enabling the
Stacking Feature” on page 293.
 Use the SHOW LICENSE BRIEF command to confirm that they
have the same feature licenses. If they have different licenses, add
or delete licenses so that they have the same feature licenses.
 Use the SHOW STACK command to compare the ID numbers of
the switches. One switch should have the ID 1 and the other ID 2.
To configure the ID numbers, perform “Setting the ID Number” on
page 297.
You might also try watching for error messages on the Console port on
one of the controller cards when you power on or reset the switches. Here
are the messages:

The following error message indicates that the two chassis have
different feature licenses. Switches cannot form a stack if they
have different licenses. Perform “Displaying the Feature Licenses”
on page 295 on both switches to determine which switch needs a
license. For example, if, after performing the procedure, you
determine that one of the switches has the premium license and
the other one does not, obtain and install the premium license on
the other unit.
