Configuring Voice VLANs
Voice VLAN allows network administrators enhance 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 to VoIP, ensuring that the quality of voice does not deteriorate if the IP traffic is received
unevenly. The system supports one Voice VLAN.
