18.7.4 GVRP Troubleshooting

The GARP counter setting for Trunk ports in both ends of Trunk link must be the same,

otherwise GVRP will not work normally. It is recommended to avoid enabling GVRP and RSTP

at the same time in switch. If GVRP needs to be enabled, RSTP function for the ports must be

disabled first.

18.8 Voice VLAN Configuration

18.8.1 Introduction to Voice VLAN

Voice VLAN is specially configured for the user voice data traffic. By setting a Voice VLAN and

adding the ports of the connected voice equipments to the Voice VLAN, the user will be able to

configure QoS (Quality of service) service for voice data, and improve the voice data traffic

transmission priority to ensure the calling quality.

The switch can judge if the data traffic is the voice data traffic from specified equipment

according to the source MAC address field of the data packet entering the port. The packet

with the source MAC address complying with the system defined voice equipment OUI

(Organizationally Unique Identifier) will be considered the voice data traffic and transmitted to

the Voice VLAN.

The configuration is based on MAC address, acquiring a mechanism in which every voice

equipment transmitting information through the network has got its unique MAC address.

VLAN will trace the address belongs to specified MAC. By This means, VLAN allows the voice

equipment always belong to Voice VLAN when relocated physically. The greatest advantage of

the VLAN is the equipment can be automatically placed into Voice VLAN according to its voice

traffic which will be transmitted at specified priority. Meanwhile, when voice equipment is

physically relocated, it still belongs to the Voice VLAN without any further configuration

modification, which is because it is based on voice equipment other than switch port.

Notice: Voice VLAN needs to associate with Hybrid attribute of the ports to work, so the ports

that may be added to Voice VLAN must be configured as Hybrid port.
