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 on
page 4-281). 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 "Spanning Tree Commands" on page 4-226 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)#
