This window appears when you select an interface and click Modify in the Voice VLAN window. Use it to change the voice VLAN settings on the selected interface.
Use the Voice VLAN list to change the voice VLAN setting to New VLAN ID, Native VLAN, None, or Untagged. If you choose New VLAN ID, a field appears for entering a VLAN ID.
This list also displays the available VLAN IDs on the device. You can select them and modify their settings.

Port Fast immediately brings a port from the blocking state into the forwarding state by eliminating the forward delay (the amount of time a port waits before changing from its STP learning and listening states to the forwarding state). The Port Fast list lets you disable Port Fast, enable it for static-access ports only, or enable it for static-access and trunk ports.
In the Appliance Trust list, select Trust if you want the IP phone to forward packets from a daisy-chained device (another IP phone or a PC) without change; select None if you want it to ignore the priority of the packets.
If the interface is on a Catalyst 3524 PWR or Catalyst 3548 XL switch, you can also select CoS. Use the spin buttons beside this selection to select a priority that will override the priority in packets from a daisy-chained device.
Click OK when you finish with the window. You return to the Voice VLAN window.
