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)#
