MAC Address Table
1.1 Overview
The MAC address table contains address information that the switch uses to forward
packets. As shown below, the table lists map entries of MAC addresses, VLAN IDs and
ports. These entries can be manually added or automatically learned by the switch. Based
on the MAC-address-to-port mapping in the table, the switch can forward packets only to
the associated port.

1.2 Supported Features
The address table of the switch contains dynamic addresses, static addresses and filtering
addresses.
Address Configurations
■
Dynamic address
Dynamic addresses are addresses learned by the switch automatically, and the switch
regularly ages out those that are not in use. That is, the switch removes the MAC address
entries related to a network device if no packet is received from the device within the aging
time. And you can specify the aging time if needed.
■
Static address
Static addresses are manually added to the address table and do not age. For some
relatively fixed connection, for example, frequently visited server, you can manually set the
MAC address of the server as a static entry to enhance the forwarding efficiency of the
switch.
■
Filtering address
Filtering addresses are manually added and determine the packets with specific source or
destination MAC addresses that will should dropped by the switch.
