Voice VLAN
Voice VLAN allows to allocate VoIP equipment into the separate VLAN. For VoIP frames, you can
specify QoS attributes for traffic prioritization. VoIP equipment frame classification is based on the
sender's OUI
(
Organizationally Unique Identifier—the first 24 bits of MAC address). Voice VLAN assigning
for port is performed automatically, when the frame with OUI from the Voice VLAN table comes to the
port. When the port is identified as Voice VLAN port, this port is added to VLAN as tagged. Voice VLAN is
applied in the following circumstances:
VoIP equipment is configured to send tagged packets, with Voice VLAN ID, configured on
the switch.
VoIP equipment sends untagged DHCP requests. DHCP server reply contains Option 132
with the VLAN ID, that is automatically assigned by the VoIP device as the VLAN for VoIP
traffic labelling (Voice VLAN ID).
