Configuring Voice VLAN

Voice VLAN enables network administrators to improve VoIP service by configuring ports to carry IP voice traffic from IP

phones on a specific VLAN. VoIP traffic has a preconfigured OUI prefix in the source MAC address. Network

administrators can configure VLANs on which voice IP traffic is forwarded. Non-VoIP traffic is dropped from the Voice

VLAN in Auto Voice VLAN Secure mode. Voice VLAN also provides QoS, ensuring that the quality of voice does not

deteriorate if the IP traffic is received unevenly. The system supports one Voice VLAN.

There are two operational modes for IP Phones:

 IP phones are configured with VLAN-mode as enabled, ensuring that tagged packets are used for all

communications.

 If the IP phone’s VLAN-mode is disabled, the phone uses untagged packets. The phone uses untagged packets

while retrieving the initial IP address through DHCP. The phone eventually uses the Voice VLAN and begins

sending tagged packets.
