• The MAC address of IP phone A is 0011-1100-0001. The phone connects to a downstream device
named PC A whose MAC address is 0022-1100-0002 and to GigabitEthernet 1/0/1 on an
upstream device named Device A.
• The MAC address of IP phone B is 0011-2200-0001. The phone connects to a downstream device
named PC B whose MAC address is 0022-2200-0002 and to GigabitEthernet 1/0/2 on Device A.
• Device A uses voice VLAN 2 to transmit voice packets for IP phone A and uses voice VLAN 3 to
transmit voice packets for IP phone B.
Configure GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 to operate 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.

Please wait... Done.
# Set the voice VLAN aging time to 30 minutes.

# (Optional.) GigabitEthernet 1/0/1 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 operate in
security mode. Configure the voice VLANs to transmit only voice packets. By default, voice VLANs
operate 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.
