    Hi,
      Is there a way to stop CONFIG ROLLBACK on the MM/MD? We are having an issue where the controller, MD, keep rolling back for some reason?

    A configuration rollback happens when a configuration change interrupts connectivity between the MD and the MM after the configuration is applied.  When the MD rolls back the configuration, it should try to apply the faulty config twice and then it should stop until you make another change to the configuration..rolling back to the previous config.

    Don't make a change that disconnects the MD from the MM.

    We are not making any changes and the controller was running perfectly fine for a year, the controller just keep going into config rollback for no reason. Again, no changes have been made to the switch or the controller side!

    I would look at the audit trail on the MM (show audit-trail) and I would open a technical support case to understand what could be happening.  I am only telling how it is designed to work.  You could have a bug.

    Just an update on this post. This is a bug where if you add more then 139 vlans on the uplink on the controller it will go on Gonfig Rollback mode. TAC working on getting a solution for this issue.
