The following command enables MAC locking both globally for the device (stack) and at the port level for ports 2:1 through 2: 5:
Slot-1 Stack.1 # enable mac-locking
Slot-1 Stack.2 # enable mac-locking ports 2:1-2:5
The following command lines enable port 2:1 for a maximum of 3 static MAC address entries. This is followed by four static MAC address creation entries. The fourth entry fails because the maximum allowed has been set to 3.
