`voice-vlan`

Creates a voice VLAN at the global level.

Syntax

voice-vlan vlan-id

no voice-vlan vlan-id

Command Default

A global voice VLAN is not configured.

Parameters

vlan-id: Specifies the VLAN identifier. The range is from 1 through 4095 (excluding all reserved VLANs).

Modes

Authentication configuration mode

Usage Guidelines

The global voice VLAN is the default VLAN for voice traffic and is used:

When the RADIUS server does not return VLAN information after authentication success.

When the RADIUS server is not reachable for first authentication and auth-timeout-action is set to success.

Any time that the RADIUS server is not reachable, auth-timeout-action is set to critical vlan, and voice-vlan is configured for critical action.

When authentication fails, auth-fail-action is set to restricted and voice-vlan is configured for restricted action.

The no form of the command removes the global voice VLAN configuration.

Examples

The following example shows how to configure VLAN 4 as the global voice VLAN.

device# configure terminal
device(config)# authentication
device(config-authen)# voice-vlan 4
