Switch C:
Switch(config)# gvrp
Switch(config)#vlan 100
Switch(Config-Vlan100)#switchport interface ethernet 1/2-6
Switch(Config-Vlan100)#exit
Switch(config)#interface ethernet 1/11
Switch(Config-If-Ethernet1/11)#switchport mode trunk
Switch(Config-If-Ethernet1/11)# gvrp
Switch(Config-If-Ethernet1/11)#exit
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.
