Cisco Catalyst 2960 Series User Manual

The switch attempts to disable the port.
If the port-disable operation is successful, the signal that triggered the port-disable is removed from the standby
stack master.
If the stack master fails before the port-disable operation completes, the port is disabled after stack master
change-over based on the original command (which is subsequently removed).
If the stack master fails before sending a CoA-ACK message, the new stack master treats the re-sent command
as a new command.
