Configure single port to ALLOW specific MAC address only

[beckfiveoh]

With the search feature presently down, I'm resorting to the posting here. We have a data port on a Cat3550 in a "public" non-trusted area that is going to be open during non-business hours. We want to lock this port down to a specific, trusted mac address of a laptop that will be used there, and when it's not plugged in, have the port essentially become useless. Can someone help with the commands necessary to implement this for only one port, as the rest of the 47 ports are behind closed doors and don't need any mac filtering going on those?

Thanks.
