Note: Note that unless you enable the
violation; the physical interface remains up, as shown below:

FTOS Behavior: Regarding
1 If the interface to be shutdown is a port channel, all the member ports are disabled in the hardware.
2 When a physical port is added to a port channel already in an Error Disable state, the new member port is
3 When a physical port is removed from a port channel in an Error Disable state, the Error Disabled state is
4 You can clear the Error Disabled state with any of the following methods:
