MAC Address Configuration
Learning the Dynamic Address
Dynamic Address
A dynamic address is the MAC address learnt automatically from the packets
received by the switch. Only the dynamic address be removed by the aging
mechanism of the address table.
Address Learning Process
In general, it maintains the MAC address table by learning the dynamic address.
The operation principle is:
The MAC address table in the switch is null and User A shall communicate with
User B. User A sends the packet to interface GigabitEthernet 0/2 and the MAC
address for User A is learnt in the MAC address table.
There is no source MAC address for User B in MAC address table. Therefore,
the switch sends the packets to all ports except for the ports of User A in
broadcast form. User C can receive the packets sent from User A and don
’t
belong to User A.

Figure3 MAC Address Table1
Upon receiving the packets, UserB will send them to UserA through interface
GigabitEthernet 0/3. The MAC address for UserA exits in the MAC address
table. Therefore, the packets are forwarded to interface GigabitEthernet 0/2 in
the unicast form and the switch learns the MAC address for UserB at the same
