Command Syntax

Parameter

Parameter

Description

gigabit-ethernet <interface-name>

Specifies the physical port of the switch.

tagged mode <tag | untag | auto>

Configure the tagged mode for the outgoing packet of a voice VLAN interface. The value could be tag, untag or auto.

tag: the outgoing packets of a voice VLAN interface be tagged with the voice VLAN ID regardless of the protocol type used between the switch and the IP phone.
untag: the outgoing packets of a voice VLAN interface be untagged regardless of the protocol type used between the switch and the IP phone.
auto: the system automatically determines whether the outgoing packet of a voice VLAN interface be tagged with the voice VLAN ID per the protocol type.

The value auto is the default and recommended value.

Usage Guidelines

For tagged mode auto,

If the packet matches the user defined OUI addresses or the OUI addresses learned from CDP and LLDP protocols, the outgoing packet from a voice VLAN interface will be untagged when the tagged mode is auto.

If the packet matches the OUI addresses learned from LLDP-MED protocol, the outgoing packet of a voice VLAN interface will be tagged with the voice VLAN ID based on the result of the LLDP-MED protocol negotiation between the switch and the IP phone when the tagged mode is auto.
- If the negotiation result of LLDP-MED protocol between the switch and the IP phone is SUCCESS, the outgoing packet of a voice VLAN interface will be tagged with the voice VLAN ID.
- Else if the negotiation result of LLDP-MED protocol between the switch and the IP phone is FAILURE, the outgoing packet of a voice VLAN interface will be untagged.

Example

Configure the outgoing packet of a voice VLAN interface ge-1/1/1 be tagged with the voice VLAN ID.
