how can i do that in a switch?
i know of the command >mac-address-table
but what exactly i need to write in order to restrict FastEthernet0/1 to work only with MAC XXXX.XXXX.XXXX ?

Hi
You need to use port-security to restrict which mac-addresses can use that port.
I have attached a link to 3560 port seurity configuration which explains the concept of port security.
If you have a different switch just search on Cisco for "switch type + port security"

Hi, [PLS RATE if HELPS]
As a continuation of Jon.Marshall post,
Cisco has very famous feature called port-security to restict Switch port access based on MAC-Address of clients connecting to it.
You can specify the Security feature in such a way like if somebody violate the Security you can instruct the Switch to Shutdown the Interface and only the Administrator can re-enable the port manually.
Refer link below for further understanding:

i know of port-security, i just want to know about the other method of associating a single MAC with a port.

Hi
You can use the mac-address-table static command. Attached is link for 3560 example.
As far as i know this does not restrict the port to just that mac-address though.

So does this prevent other MAC addresses to access the port?
