5-4-6-3. Port Security

A port in security mode will be “locked” with address learning blocked. Only
the incoming packets with SMAC already existing in the address table can
be forwarded normally. The user 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. Enter the settings, and then
click
