Blocking mac addresses in Catalyst(3550,5500,6513) switches

Need help to block mac addresses of infected PCs.

Disabling port does not help much since some smart ones connect to other switch ports. Blocking IP addresses also does not helps much.

Many thanks.

You could disable the unused ports so they cannot move to them. Or you can try port security to restrict access to known good PC's.

OK, guess that's I'm looking for.

Many thanks.
