Managing the MAC
Address Table
The Switch 8800 maintains a MAC address table for fast forwarding of packets. A
table entry includes the MAC address of a device and the port ID of the switch
connected to it. The switch learns dynamic entries when it receives a data frame
from a port (assumed as port A). The switch analyzes the source MAC address and
considers that the packets destined for the source MAC address can be forwarded
through port A. If the MAC address table contains the MAC_SOURCE, the switch
updates the corresponding entry, otherwise, it adds the new MAC address (and
the corresponding forwarding port) as a new entry to the table.
The system forwards the packets whose destination addresses can be found in the
MAC address table. The network device responds after receiving a broadcast
packet and the response contains the MAC address of the device, which the
switch learns and adds in the MAC address table. After this, subsequent packets
destined for the same MAC address can be forwarded directly.
