switchport voice vlan rule

This command selects a method for detecting VoIP traffic on a port. Use the no form to disable the
detection method on the port.

Syntax

[no] switchport voice vlan rule {oui | lldp}

oui - Traffic from VoIP devices is detected by the Organizationally Unique Identifier (OUI) of
the source MAC address.

lldp - Uses LLDP to discover VoIP devices attached to the port.

Default Setting

OUI: Enabled
LLDP: Disabled

Command Mode

Interface Configuration

Command Usage

When OUI is selected, be sure to configure the MAC address ranges in the Telephony OUI list
(see the

voice vlan mac-address

command. MAC address OUI numbers must be configured in

the Telephony OUI list so that the switch recognizes the traffic as being from a VoIP device.

LLDP checks that the “telephone bit” in the system capability TLV is turned on. See

“”

on

page 505 for more information on LLDP.

Example

The following example enables the OUI method on port 1 for detecting VoIP traffic.
