Voice VLAN Window

This window is available for Catalyst 2900 XL and 3500 XL switches only. It appears when you choose VLAN > Voice VLAN on the menu bar. You can also click here to launch it.

Begin by selecting a host from the Host Name list. The settings you see in the window are for the interfaces on the selected device.

To change the settings for one or more interfaces:

  1. Select the rows that the interfaces are in.
  2. Click Modify. Then use the Modify Voice VLAN window.

To return the settings for one or more interfaces to their defaults:

  1. Select the rows that the interfaces are in.
  2. Click Set Defaults.

This table explains the voice VLAN settings and gives their defaults.

Column Explanation
Interface
The interfaces on the selected device.
Voice VLAN

The voice VLAN setting for the interface. It can be:

  • A value from 1 to 1001 that identifies the VLAN.
  • Native VLAN--the native VLAN for the device is the voice VLAN.
  • None--the interface does not belong to a voice VLAN.
  • Untagged--a CoS value should not be added to untagged packets.

The default is None.

VLAN mode The access mode for the interface. Possible values are 802.1Q Trunk, Static Access, and ISL Trunk. The default is Static Access.
Appliance Trust

Specifies what to do with packets from a device that is daisy-chained to an IP phone -- either another IP phone or a PC. A numeric value represents a priority that overrides the priority of packets from the daisy-chained device. Trust means that priority of packets from the device is forwarded without change. None means that the priority of packets from the device is ignored. The default is None.

Note: The priority of a packet from a daisy-chained device can be overridden only if the IP phone is connected to a Catalyst 3524 PWR or Catalyst 3548 XL switch.

Port Fast A feature that immediately brings an interface from the blocking state into the forwarding state by eliminating the forwarding delay -- either Enabled or Disabled. The default is Disabled.
IP Phone Shows whether an IP phone is connected to the interface or not -- either Connected or Not Connected.
