3424 source MAC

Question

Is it possible to setup an ACL that will block a source MAC?  I think that is what I want to do anyway, maybe I am thinking about it in the wrong way.  We have a few PC that are connecting to our network that don't belong on it and I want to prevent them from being able to do anything. Seems to be blocking the MAC address would be the way to do this.

From the CLI reference guide:

Console(config)# mac access-list macl-1

Console (config-mac-acl)# deny 66:66:66:66:66:66

Console(config-mac-acl)# exit

Console(config)# interface vlan 2
Console(config-if)# service-acl input macl-1

Networking General

3424 source MAC
