10.2.4 GVRP Troubleshooting
The GARP counter setting in for Trunk ports in both ends of Trunk link must be the same, otherwise GVRP will
not work properly. It is recommended to avoid enabling GVRP and RSTP at the same time in switch. If GVRP
is to be enabled, RSTP function for the ports must be disabled first.
10.3 Dot1q-tunnel Configuration
10.3.1 Introduction to Dot1q-tunnel
Dot1q-tunnel is also called QinQ (802.1Q-in-802.1Q), which is an expansion of 802.1Q. Its dominating idea is
encapsulating the customer VLAN tag (CVLAN tag) to the service provider VLAN tag (SPVLAN tag). Carrying
the two VLAN tags the packet is transmitted through the backbone network of the ISP internet, so to provide a
simple layer-2 tunnel for the users. It is simple and easy to manage, applicable only by static configuration,
and especially adaptive to small office network or small scale metropolitan area network using layer-3 switch
