Create A Voice Vlan - TRENDnet TPE-3012LS User Manual

TRENDnet User's Guide
It is possible to find more than one OUI from the same manufacturer among the IP
phones you are installing. It is also possible that your IP phones are from two or more
different manufacturers in which case you will find different OUIs for each
manufacturer. If you identify more than one OUI among the IP phones being installed,
then one MAC address representing each OUI must be configured in the voice VLAN.
Dynamic Auto-Detection vs Manual Ports
Prior to configuring the voice VLAN, you must configure a tagged VLAN which is the
basis for the voice VLAN configuration. The VLAN must be configured with one or more
tagged or untagged ports that will serve as the voice VLAN uplink/downlink. By default,
a tagged or untagged port is a static member of a tagged VLAN. The ports that you
choose to configure as dynamic Auto-Detection ports must be connected directly to an
IP phone. When you initially define the ports of a tagged VLAN for your voice VLAN
configuration, they must be configured as a "Not Member" ports. The "Not Member"
ports are eligible to dynamically join the voice VLAN when voice data is detected with a
predefined OUI in the source MAC address. The port will leave the voice VLAN after a
specified timeout period. This port behavior is configured with the voice VLAN Auto-
Detection feature.
For the Auto-Detection feature to function, your IP phone(s) must be capable of
generating 802.1Q packets with embedded VLAN ID tags. You must manually configure
your IP phone(s) for the same VLAN ID as the switch's voice VLAN ID. When voice data is
detected on one of the "Not Member" ports, the packets from the IP phone will contain
the voice VLAN ID so they are switched within the switch's voice VLAN.
One or more ports in your voice VLAN must be configured as Static tagged or untagged
members. Static VLAN members are permanent member ports of the voice VLAN and
there is no dependency on the configuration of the devices connected to the ports.
These ports might be connected to other voice VLAN network nodes such as other
Ethernet switches, a telephone switch, or a DHCP server. The voice VLAN Auto-
Detection feature cannot be enabled on Static tagged or tagged ports.
Note: Any Static tagged members of the voice VLAN are required to have the port VLAN
ID (PVID) configured to be the same as the voice VLAN ID. This ensures that all untagged
packets entering the port are switched within the voice VLAN as the voice data passes
through the switch.
If the IP phone(s) that you are installing cannot be configured with a VLAN ID, then the
switch ports should be configured as Static tagged ports within the voice VLAN.
Note: Link Layer Discovery Protocol for Media Endpoint Devices (LLDP- MED) is not
supported on the switch. Each IP phone that is VLAN aware should be manually

configured for the VLAN ID that matches your voice VLAN ID. Each of the voice VLAN
ports connected to an IP phone should be configured as "Not Member" ports of the
tagged VLAN.

Create a Voice VLAN

Voice VLAN > Voice VLAN > Property
Note: Prior to configuring your voice VLAN, you must first configure a tagged VLAN. This
VLAN will be used as a basis for your voice VLAN.
1. Log into your switch management page (see
on page 11).
2. Click on VLAN, click on Voice VLAN, and click on Property.
3. Review the settings. Click Apply to save the configuration settings.
Use the following procedure to configure voice VLAN:
•
State – Checking the Enable option will enable the Voice VLAN feature.
Unchecking the option will disable the Voice VLAN feature.
•
VLAN – Click the drop-down list to select the VLAN assigned as the designated
voice VLAN ID.
Note: The VLAN must be created under VLAN and VLAN Configuration first
before the VLANs are available in the drop-down list.
•
CoS / 802.1p Remarking – Check the Enable option to attach the specified
802.1p CoS priority tag to Voice VLAN traffic. Click the drop-down list to select
the 802.1p priority tag to assign to voice VLAN traffic.
Note: For the CoS priority to be effective, QoS must be enabled.
•
Port Aging Time - This parameter indicates the amount of time, in hours, after
the last IP phone's OUI was received on a port, after which this port will be
removed from the voice VLAN. The range is 30 to 65536 minutes.
