Tp-Link T3700G-28TQ V1 [284/415] Voice vlan

272

UL-Frame Rate : Select the bandwidth for receiving UL-

Frame on the port. The

packet traffic exceeding the bandwidth will be discarded. Select

Disable to disable the UL-Frame control function for the port.

LAG: Displays the LAG number which the port belongs to.

Note:

If you enable storm control feature for the ingress rate limit-enabled port, ingress rate limit feature

will be disabled for this port.

12.3 Voice VLAN

Voice VLANs are configured specially for voice data stream. By configuring Voice VLANs and

adding the ports with voice devices attached to voice VLANs, you can perform QoS-related

configuration for voice data, ensuring the transmission priority of voice data stream and voice

quality.



OUI Address (Organizationally unique identifier address)

The switch can determine whether a received packet is a voice packet by checking its source MAC

address. If the source MAC address of a packet complies with the OUI addresses configured by

the system, the packet is determined as voice packet and transmitted in voice VLAN.

An OUI address is a unique identifier assigned by IEEE (Institute of Electrical and Electronics

Engineers) to a device vendor. It comprises the first 24 bits of a MAC address. You can recognize

which vendor a device belongs to according to the OUI address. The following table shows the

OUI addresses of several manufacturers. The following OUI addresses are preset of the switch by

default. The OUI Address entries below can be modified manually.

Number

1 00-01-E3-00-00-00 Siemens phone

2 00-03-6B-00-00-00 Cisco phone

3 00-04-0D-00-00-00 Avaya phone

4 00-60-B9-00-00-00 Philips/NEC phone

Port Voice VLAN Mode

A voice VLAN can operate in two modes: automatic mode and manual mode.

Automatic Mode: In this mode, the switch automatically adds a port which receives voice packets

to voice VLAN and determines the priority of the packets through learning the source MAC of the

UNTAG packets sent from IP phone when it is powered on. The aging time of voice VLAN can be

configured on the switch. If the switch does not receive any voice packet on the ingress port within
