Web Configuration & Operation
Forced: Enable Voice VLAN feature on a particular port.
Security: Enable or disable security filtering feature on a per port basis. When enabled, any non-VoIP packets received on
a port with Voice VLAN ID will be discarded. VoIP traffic is identified by source MAC addresses configured in the
telephony OUI list or through LLDP which is used to discover VoIP devices attached to the switch.
Discovery Protocol: Select a method for detecting VoIP traffic. By default, OUI is used.
OUI: Traffic from VoIP devices is detected by the Organizationally Unique Identifier (OUI) of the source MAC address.
OUI numbers are assigned to manufacturers and form the first three octets of a device MAC address. 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: Use LLDP (IEEE 802.1ab) to discover VoIP devices attached to a port. LLDP checks that the “telephone bit” in
the system capability TLV is turned on or not.
Both: Use both OUI table and LLDP to detect VoIP traffic on a port.
4.18.2 OUI
