Figure-1 MAC Address Entry
 State: Dynamic,static or filtering address.
 VLAN: VLAN to which the MAC address belongs;
 MAC address: the MAC address information in the entry;
 Interface: the information of the interface with which the MAC address is
correspondent.
The MAC address entries are updated and maintained by the following two
ways:
 Learning the Dynamic Address
 Configuring the Dynamic Address Manually
The switch searches for the corresponding outgoing forward interface according
to the destination MAC address and the VLAN ID for the message in the MAC
address table, and then forwards the messages in unicast, multicast and
broadcast way.
 Unicast forwarding: if the switch searches for the corresponding entry of the
packet destination MAC address and VLAN ID in the MAC address table and
the outgoing forward interface is sole, the packets are forwarded through this
interface.
 Multicast forwarding: if the switch searches for the corresponding entry of the
packet destination MAC address and VLAN ID in the MAC address table and
this entry is correspondent with a group of outgoing forward interfaces, the
packets are forwarded through the interfaces directly.
 Broadcast forwarding: if the switch receives the packets destined to ffff.ffff.ffff, or
it can not search for the corresponding entry in the MAC address table, the
packets are sent to the VLAN to which belongs and forwarded through the
outgoing interfaces except for the incoming interface.
Note
This chapter describes management of dynamic, static and filtering
addresses. For the management of multicast address, please refer to IGMP
