Automatic voice VLAN mode configuration example

Network requirements
As shown in Figure
The MAC address of IP phone A is 001 1- 1 100-0001. The phone connects to a downstream device
•
named PC A whose MAC address is 0022- 1 100-0002 and to GigabitEthernet 1/0/1 on an
upstream device named Device A.
The MAC address of IP phone B is 001 1-2200-0001. 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 voice VLAN 3 to transmit
•
voice packets for IP phone B.
Configure GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 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.

Configuration procedure
# Create VLAN 2 and VLAN 3.
<DeviceA> system-view
[DeviceA] vlan 2 to 3
# Set the voice VLAN aging time to 30 minutes.
[DeviceA] voice vlan aging 30
# 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 work in security mode to
transmit only voice packets. By default, voice VLANs work in security mode (optional).
[DeviceA] voice vlan security enable
# Configure the allowed OUI addresses as MAC addresses prefixed by 001 1- 1 100-0000 or 001 1-2200-
0000. Device A identifies packets whose MAC addresses match any of the configured OUI addresses as
voice packets.
