Users Manual Part 1
Mode: Allows you to define the Voice VLAN mode.
Auto: Automatically advertises the Voice VLAN to connected devices via the LLDP-MED
protocol.
OUIs: Determines whether a received packet is a voice packet by checking its source
MAC address.
Switch Voice VLAN: Allows you to choose what VLAN is used for Voice VLAN. You can set
up VLANs in Port Settings.
QoS Priority:
Lets you define whether the switch will use the Quality of Service CoS value of
the incoming packet, or tag the packet with a CoS value between 1-7.
OUIs:
VoIP traffic has a pre-configured Organizationally Unique Identifier (OUI) prefix in the
source MAC address. You can manually add a specific manufacturer's MAC address and
description to the OUI table. All traffic received on the Voice VLAN ports from the specific IP
phone with a listed OUI is forwarded on the voice VLAN.

of network congestion. Switches implement this by reading tagged packets and prioritizing
them accordingly. Packets are classified using Class of Service (CoS) on the data link layer,
and
Differentiated Services Code Points (DSCP)
on the network layer, mapped to a queue,
then sent out accordingly as per QoS.
