MAC address restrictions are pretty bad because anyone can easily clone a MAC address. Maybe you should start another question that asks about what you are trying to achieve by using port security. There may be other, better ways to accomplish it. | |

This is enabled on the ports individually. You don't want to do this on trunk ports, for example, only on access ports. You could use the interface range macro command to apply it to multiple ports at once.
