• 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 4/0/2 on Router A.

• Router 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 GigabitEthernet4/0/1 and GigabitEthernet 4/0/2 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 automatically removed from the corresponding voice VLAN.

Configuration procedure

# Create VLAN 2 and VLAN 3.

<RouterA> system-view

[RouterA] vlan 2 to 3

Please wait... Done.

# Set the voice VLAN aging time to 30 minutes.

[RouterA] voice vlan aging 30

# (Optional.) GigabitEthernet 4/0/1 might 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, Router A identifies packets whose MAC addresses match any of the

configured OUI addresses as voice packets.

# (Optional.) Configure GigabitEthernet 4/0/1 to operate in automatic voice VLAN assignment mode.

By default, a port operates in automatic voice VLAN assignment mode.
