ABSTRACT:
The present invention features embodiments of automatically re-enabling a disabled port or physical media interface by monitoring the link status of the physical layer interface. Any change in the link status automatically re-enables a previously disabled port, thereby permitting data coming in through the previously disabled port to be admitted into the switch and automatically forwarded or routed/switched, without the network administrator manually issuing any commands to manually re-enable the port.
