When a dot1p priority is associated with the Voice VLAN port instead of a VLAN ID, then the priority information is passed onto the VOIP phone using the LLDP-MED mechanism. By this method, the voice data coming from the VOIP phone is tagged with VLAN 0 and with the exchanged priority; thus regular data arriving on the switch is given the default priority of the port (default 0), and the voice traffic is received with a higher priority.

You can configure the switch to override the data traffic CoS. This feature can override the 802.1 priority of the data traffic packets arriving at the port enabled for Voice VLAN. Therefore, any rogue client that is also connected to the Voice VLAN port does not deteriorate the voice traffic.

Interaction with LLDP-MED

The interactions with LLDP-MED are important for Voice VLAN:

LLDP-MED notifies the Voice VLAN component of the presence and absence of a VoIP phone on the network.

The Voice VLAN component interacts with LLDP-MED for applying VLAN ID, priority and tag information to the VoIP phone traffic.

For release 2.0 and earlier, the Voice VLAN feature can only be used by IP phones that support LLDP-MED, e.g. 4610SW Avaya phones.

Example#1: Configuring Voice VLAN

The commands in this example create a VLAN for voice traffic with a VLAN ID of 25. Then, Voice VLAN is administratively enabled on the switch. Finally, port 1/g12 is set to an 802.1Q VLAN and then enabled for Voice VLAN traffic.

console#configure console(config)#vlan database console(config-vlan)#vlan 25 console(config-vlan)#exit

console(config)#voice vlan

console(config)#interface ethernet 1/g12 console(config-if-1/g12)#switchport mode general console(config-if-1/g12)#voice vlan 25 console(config-if-1/g12)#exit console(config)#exit
