5.6 MAC Address Table

The MAC Address Table is a table of node addresses that the switch automatically builds by “learning.” It performs this task by monitoring the packets that pass through the switch, checking the source and destination addresses, and then recording the source address information in the table. To see the table, type the following command in privileged mode:

Switch#	show mac-address-table	Type	Ports
Vlan	Mac Address	Type	Ports
----	-----------------	----	-----
3	00:00:1C:01:00:09	Dynamic	eth13
1	00:00:94:00:00:10	Dynamic	eth9
1	00:00:94:A0:B6:7B	Dynamic	eth9
1	00:00:94:AA:64:37	Dynamic	eth9
1	00:00:94:D2:53:79	Dynamic	eth9
--	00:00:94:D2:56:EA	Self	--
1	00:0A:27:AE:50:66	Dynamic	eth9
1	00:50:FC:94:00:0D	Dynamic	eth9

The switch uses the information in this table to decide whether a frame should be forwarded to a particular destination port or “flooded” to all ports other than to the received port. Each entry consists of three parts: the MAC address of the device, the port number on which it was received, and the VLAN number. The MAC address of the switch is identified as “self”.

By default, entries in the switch's MAC address table expire after 300 seconds. To change this value, use the following command in global configuration mode:

Switch(config)# mac-address-table aging-time

The range is 10–1,000,000 seconds. A value of 0 disables aging.
