Automatic voice VLAN assignment mode configuration example
Network requirements
As shown in Figure 55, Device A transmits traffic from IP phones and hosts.
For correct voice traffic transmission, perform the following tasks on Device A:
Configure voice VLANs 2 and 3 to transmit voice packets from IP phones A and B, respectively.
Configure Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 to operate in automatic voice VLAN assignment mode.
Add MAC addresses of IP phones A and B to the device for voice packet identification. The mask of the two MAC addresses is FFFF-FF00-0000.

Configuration procedure
Configure voice VLANs:
# Create VLANs 2 and 3.
<DeviceA> system-view [DeviceA] vlan 2 to 3
# Set the voice VLAN aging timer to 30 minutes.
[DeviceA] voice-vlan aging 30
# Configure voice VLANs to operate in security mode to transmit only voice packets.
[DeviceA] voice-vlan security enable
# Add MAC addresses of IP phones A and B to the device with the mask FFFF-FF00-0000.
[DeviceA] voice-vlan mac-address 0011-1100-0001 mask ffff-ff00-0000 description IP phone A [DeviceA] voice-vlan mac-address 0011-2200-0001 mask ffff-ff00-0000 description IP phone B
Configure Ten-GigabitEthernet 1/0/1:
# Configure Ten-GigabitEthernet 1/0/1 as a hybrid port.
[DeviceA] interface ten-gigabitethernet 1/0/1 [DeviceA-Ten-GigabitEthernet1/0/1] port link-type hybrid
# Configure Ten-GigabitEthernet 1/0/1 to operate in automatic voice VLAN assignment mode.
[DeviceA-Ten-GigabitEthernet1/0/1] voice-vlan mode auto
# Enable voice VLAN on Ten-GigabitEthernet 1/0/1 and configure VLAN 2 as the voice VLAN for it.
[DeviceA-Ten-GigabitEthernet1/0/1] voice-vlan 2 enable [DeviceA-Ten-GigabitEthernet1/0/1] quit
Configure Ten-GigabitEthernet 1/0/2:
# Configure Ten-GigabitEthernet 1/0/2 as a hybrid port.
[DeviceA] interface ten-gigabitethernet 1/0/2 [DeviceA-Ten-GigabitEthernet1/0/2] port link-type hybrid
# Configure Ten-GigabitEthernet 1/0/2 to operate in automatic voice VLAN assignment mode.
[DeviceA-Ten-GigabitEthernet1/0/2] voice-vlan mode auto
# Enable voice VLAN on Ten-GigabitEthernet 1/0/2 and configure VLAN 3 as the voice VLAN for it.
[DeviceA-Ten-GigabitEthernet1/0/2] voice-vlan 3 enable [DeviceA-Ten-GigabitEthernet1/0/2] quit
