Question : cisco catalyst 2900 mac filtering problem

Hello,
We have a network using a cisco 2620 router, and a small switch. There are various pc's on the network that need not be there. After countless attempts to eliminate them with access-lists in the router, I came across something on the web referring to mac-filtering using the catalyst line of switch. I purchased a catalyst 2900 xl (2912xl) and now wish to create a config utilizing this. What I would like to do is allow only a specified set of Mac-addresses to be able to pass any traffic through the switch. This would eliminate the PC's that are not supposed to be on the network from ever arriving at our router. The number of mac-addresses would be around 30 , and I would be adding and removing various ones occasionally. Any help would be greatly appreciated.

Thanks,
Corey

I have port security enabled on a 2924XL running IOS 12.0.

The command is:

mac-address-table secure 0000.1111.2222 FastEthernet0/x vlan Y
                                        ^this is the permittec mac    ^interface and vlan

Repeat this command 20 times, once for each MAC address.
