Designating a Voice VLAN

On 2900 XL and 3500 XL switches, you can designate a voice VLAN, a VLAN that carries voice traffic from IP phones. Using a VLAN for this specialized purpose lets you control the priority of the traffic and expedite throughput.

To designate a VLAN as a voice VLAN, choose VLAN > Voice VLAN and use the Voice VLAN window.
