3.21 Voice VLAN
Nowadays, in the enterprise network, VoIP devices are commonly deployed to save operational cost due to its easy-
to-setup feature and convenience. However, while deploying VoIP devices, it is recommended that VoIP traffic is
separated from data traffic. By isolating traffic, VoIP traffic can be assigned to have the highest priority while
forwarding so that higher voice quality can be achieved without encountering situations like excessive packet delays,
packet loss, and jitters. Moreover,
This switch provides Voice VLAN feature that enables voice traffic to be forwarded on the voice VLAN. The user can
also overwrite traffic priority by assigning higher traffic class value to voice traffic. Voice traffic can be detected on a
port by using LLDP (IEEE 802.1ab) to discover VoIP devices attached to the switch or from devices’ OUI
(Organizationally Unique Identifier). When voice packets are detected on a port, the switch automatically assigns the
port as a tagged member of the Voice VLAN and forward packets based on configurations set in Voice VLAN
configuration page.
The Voice VLAN section provides that following two sub menus:
