The switch allows you to specify a Voice VLAN for the network and set a
service 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 as a tagged
member the Voice VLAN. Alternatively, switch ports can be manually
configured.
Use the Voice VLAN Configuration page to configure the switch for VoIP
traffic. First enable automatic detection of VoIP devices attached to the
switch ports, then set the Voice VLAN ID for the network. The Voice VLAN
aging time can also be set to remove a port from the Voice VLAN when
VoIP traffic is no longer received on the port.

The priority of any received VoIP packet is overwritten with the new

Default: 7)
The switch provides eight priority queues for each port. For information
on how these queues are used, see
on page 196.
