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 ).
