Configuring VoIP Traffic Ports
– 255 –
■
Auto – The port will be added as a tagged member to the Voice
VLAN when VoIP traffic is detected on the port. You must select a
method for detecting VoIP traffic, either OUI or 802.1ab (LLDP).
When OUI is selected, be sure to configure the MAC address ranges
in the Telephony OUI list.
■
Manual – The Voice VLAN feature is enabled on the port, but the
port must be manually added to the Voice VLAN.
◆
Security – Enables security filtering that 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. (Default: Disabled)
◆
Discovery Protocol – Selects a method to use for detecting VoIP
traffic on the port. (Default: OUI)
■
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 – Uses LLDP (IEEE 802.1ab) to discover VoIP devices
attached to the port. LLDP checks that the “telephone bit” in the
system capability TLV is turned on. See
for more information on LLDP.
◆
Priority – Defines a CoS priority for port traffic on the Voice VLAN. The
priority of any received VoIP packet is overwritten with the new priority
when the Voice VLAN feature is active for the port. (Range: 0-6;
Default: 6)
◆
Remaining Age – Number of minutes before this entry is aged out.
