Device A uses voice VLAN 2 to transmit voice packets for IP phone A and voice VLAN 3 to transmit 

voice packets for IP phone B. 

Configure GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 to work in automatic voice VLAN 

assignment mode. In addition, if one of them has not received any voice packet in 30 minutes, the port 

is removed from the corresponding voice VLAN automatically.

# Since GigabitEthernet 2/0/1 may receive both voice traffic and data traffic at the same time, to ensure 

the quality of voice packets and effective bandwidth use, configure voice VLANs to work in security 

mode, that is, configure the voice VLANs to transmit only voice packets. (Optional. By default, voice 

VLANs work in security mode.)

# Configure the allowed OUI addresses as MAC addresses prefixed by 0011-1100-0000 or 

0011-2200-0000. In this way, Device A identifies packets whose MAC addresses match any of the 

configured OUI addresses as voice packets.
