Configuring Voice VLANs
– 503 –
Command Usage
â—† 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.
â—† When enabled, be sure the MAC address ranges for VoIP devices are configured
in the Telephony OUI list (voice vlan mac-address).
