You can configure MAC addresses for the switch. The switch uses an aging mechanism, defined by a configurable aging timer, so if an address remains inactive for a specified number of seconds, it is removed from the address table. The address table can store a number of unicast and multicast address entries without flooding any frames. A multicast address can accept more than one interface as its destination. In addition, you can enter a multicast address as a statically configured MAC address. These static MAC entries are retained across a reboot of the switch. You can also enter a MAC address, which is termed a static MAC address, into the table. The switch then forwards subsequent frames to a single LAN port without flooding all LAN ports.
When the destination station replies, the switch adds its relevant MAC source address and port ID to the address table. When the switch receives a frame for a MAC destination address not listed in its address table, it floods the frame to all LAN ports of the same VLAN except the port that received the frame. The switch dynamically builds the address table by using the MAC source address of the frames received. When the switch receives a frame, it associates the media access control (MAcC) address of the sending network device with the LAN port on which it was received. To switch frames between LAN ports, the switch maintains an address table.
