Configuring GARP/GVRP 65

■When an Ethernet port registration type is set to normal, the dynamic and manual creation, registration, and logout of VLAN are allowed on this port.

■When one trunk port registration type is set to fixed, the system adds the port to the VLAN if a static VLAN is created on the switch and the trunk port allows the VLAN passing. GVRP also adds this VLAN item to the local GVRP database, one link table for GVRP maintenance. However, GVRP cannot learn dynamic VLAN through this port. The learned dynamic VLAN from other ports of the local switch will not be able to send statements to the outside through this port.

■When an Ethernet port registration type is set to forbidden, all the VLANs except VLAN1 are logged out and no other VLANs can be created or registered on this port.

Perform the following configurations in Ethernet port view.
