Use the no form of the command to disable hitless stacking failover. The change takes effect immediately.

The hitless-failover enable and no hitless-failover enable commands must be executed from the active stack controller.

You must assign a stack mac address to the device using the stack mac address command before you can execute the hitless-failover enable command.
