Configuring the MAC address table
About the MAC address table
An Ethernet device uses a MAC address table to forward frames. A MAC address entry includes a destination MAC address, an outgoing interface, and a VLAN ID. When the device receives a frame, it uses the destination MAC address of the frame to look for a match in the MAC address table.
· The device forwards the frame out of the outgoing interface in the matching entry if a match is found.
· The device floods the frame in the VLAN of the frame if no match is found.
