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

).
