To SWITCH frames between LAN ports efficiently, the switch maintains an address table called MAC address Table or CAM Table (Content Addressable Memory Table). When the switch receives a frame, source MAC address is learned and recorded in the CAM table along with the port of arrival, VLAN and TIME stamp. The switch dynamically builds the MAC address table by using the Source MAC address of the frames received. Than this table is USED by switch to determine where to forward trafic on a LAN.
