1.5.4 Static MAC Address
The switch provides Static MAC Address setup function. The static MAC addresses are the MAC addresses which are setup by LAN admin- istrators and are not learned by the switch automatically.
The static addresses are stored and referred in switch MAC address table permanently regardless of whether the MAC addresses are physi- cally disconnected to the switch.
Applying this function with port security function allows LAN adminis- trator to build a protection mechanism that let switch only serves granted devices.
Static MAC address related settings:
Mac Address : Static Ethernet MAC address (12 digits)
Port num : The port number where the MAC address is located
Vlan ID : The associated Vlan ID to the address, if 802.1Q VLAN is enabled.
1.5.5 Port Security
A port in security mode does not learn any source MAC address (SA). Only the incoming packets with SA existing in the switch static MAC address table can be forwarded normally. Otherwise, the packets are dropped. This features provides a protection mechanism to restrict the devices link to the switch port. Only devices with valid MAC addresses can be served by the switch.
