2.4.4 Port Security
A port in security mode will be "locked" without
permission of address learning. Only the incoming packets with
SMAC already existing in the address table can be forwarded
normally. You can disable the port from learning any new MAC
addresses, then use the static MAC addresses screen to define a
list of MAC addresses that can use the secure port.
