License Mismatch

A stack might have a failed node even though the show licenses command shows that all nodes are running the same license and/or feature packs.

To fix a license mismatch, do the following:

  1. At the master node's console, enter show slot slot_number repeatedly until you find the slot node that is failing.


    When you are creating a stack, a blinking orange MGMT light usually indicates a license mismatch on a master-capable standby node.
  2. Enter unconfigure stacking at the master node to unconfigure the stack.
  3. After making a connection to the failed switch's slot, update the license information for that node:
    1. For universal platforms, licenses can be uninstalled or revoked using the following command:

      uninstall license [{file} | {product}] {filename} | {productname}] [{withhold} | {revoke}]

      Select revoke.
    2. Enter reboot
    3. Obtain the correct license information for the failed switch, then enter # enable license license_key (where license_key has the format xxxx-xxxx-xxxx-xxxx-xxxx).
      For more information about licensing for stack nodes, see Managing Licenses on a Stack.
  4. Enter show stacking and enable stacking to re-enable the stack.


    Only those switches that are master-capable require compatible licenses be installed.
