[c-nsp] Blocking a Mac address at a router interface

[Chris Moore - GMD]

Hi all,
 
This seems like it should be super-easy, but I just can't seem to figure it
out!
 
I have a branch office served by a 1721 router. I have a guy there with his
own laptop that he keeps connecting to the network against company policy,
changing his IP to evade filters. I know, we should just fire the guy, but
company politics, not my decision, etc,etc.......Anyhoo, how can I block his
mac at the 1721's Ethernet interface? Unfortunately the cheapo switch in
place fails to provide adequate port security. 
 
Thanks,
 
Chris
