Automatic voice VLAN assignment mode configuration example

As shown in Figure 50, 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.

1. 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
   

2. 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
   

3. 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
   

# Display the OUI addresses and their masks and descriptions.

[DeviceA] display voice-vlan mac-address
OUI Address     Mask            Description
