56.9.1 GVRP Command Examples
This example shows the OLT’s GVRP settings.
This example turns off GVRP on ports ge-5-1 ~ ge-5-4.
56.10 Port VLAN Trunking
Enable VLAN trunking on a port to allow frames belonging to unknown VLAN groups to pass through
that port. This is useful if you want to set up VLAN groups on end devices without having to configure the
same VLAN groups on intermediary devices.
The following figure describes VLAN trunking. Suppose you want to create VLAN groups 1 and 2 (V1 and
V2) on devices A and B. Without VLAN trunking, you must configure VLAN groups 1 and 2 on all
intermediary switches C, D and E; otherwise they will drop frames with unknown VLAN group tags.
However, with VLAN trunking enabled on a port(s) in each intermediary switch you only need to create
VLAN groups in the end devices (A and B). C, D and E automatically allow frames with VLAN group tags
1 and 2 (VLAN groups that are unknown to those switches) to pass through their VLAN trunking port(s).
