6.24 Unicast Address Configuration and Query
6.24.1 Overview
When forwarding a packet, the switch searches for the forwarding port in the MAC address
table based on the destination MAC address of the packet.
A MAC address can be either static or dynamic.
Static MAC address are configured. They have the highest priority (not overridden by
dynamic MAC addresses) and are permanently valid.
Dynamic MAC addresses are learned by the switch in data forwarding, which are valid only
for a certain period. The switch periodically updates its MAC address table. When receiving
a data frame to be forwarded, the switch learns the source MAC address of the frame,
establishes a mapping with the receiving port, and queries the forwarding port in the MAC
address table based on the destination MAC address of the frame. If a match is found, the
switch forwards the data frame from the corresponding port. If no match is found, the switch
broadcasts the frame in its broadcast domain.
