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.
voice vlan This command enables VoIP traffic detection and defines the Voice VLAN
ID. Use the no form to disable the Voice VLAN.
