Abstract
An interface device enables an external device connected to a network switch to be disabled. The interface device receives and transmits data to an external device which makes data forwarding decisions. When a disable signal is received by the network switch, the disable signal is transmitted to the external device over an existing data path. The external device returns an acknowledgement signal over an existing path to the switch. A timer is included as a failsafe mechanism in case the external device does not return an acknowledge signal. The timer waits a predetermined period of time and continues the shut down of the network switch as if the acknowledge signal was received.
