Configuring Voice VLANs
The switch allows you to specify a Voice VLAN for the network and set a CoS priority
for the VoIP traffic. VoIP traffic can be detected on switch ports by using the source
MAC address of packets, or by using LLDP (IEEE 802.1AB) to discover connected
VoIP devices. When VoIP traffic is detected on a configured port, the switch
automatically assigns the port to the Voice VLAN. Alternatively, switch ports can be
manually configured.
