Command Usage
• Security filtering discards any non-VoIP packets received on the port that are
tagged with 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.
