Configuring VoIP Traffic Ports
•
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 vendors 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
on page 938 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.
The Remaining Age starts to count down when the OUI’s MAC address expires from the MAC
address table. Therefore, the MAC address aging time should be added to the overall aging
time. For example, if you configure the MAC address table aging time to 30 seconds, and the
voice VLAN aging time to 5 minutes, then after 5.5 minutes, a port will be removed from voice
VLAN when VoIP traffic is no longer received on the port. Alternatively, if you clear the MAC
address table manually, then the switch will also start counting down the Remaining Age.
Interface
To configure VoIP traffic settings for a port:
1. Click Traffic, VoIP.
2. Select Configure Interface from the Step list.
3. Configure any required changes to the VoIP settings each port.
4. Click Apply.
