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" on page 933 for more information on
LLDP.

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)#

Security filtering discards any non-VoIP packets received on the port
that are tagged with the voice VLAN ID. VoIP traffic is identified by
source MAC addresses configured in the Telephony OUI list, or through
LLDP that discovers VoIP devices attached to the switch. Packets
received from non-VoIP sources are dropped.
◆
When enabled, be sure the MAC address ranges for VoIP devices are
configured in the Telephony OUI list ( voice vlan mac-address ).
