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

• lldp - Uses LLDP to discover VoIP devices attached to the port.
Default Setting
OUI: Enabled
LLDP: Disabled

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 “LLDP Commands” for more
information on LLDP.
Example
The following example enables the OUI method on port 1 for detecting VoIP traffic.
Console(config)#interface ethernet 1/1
Console(config-if)#switchport voice vlan rule oui
Console(config-if)#
