Configuration Procedure of VLAN VPN Function: Step Operation Description 1 Enable VPN mode. Required. On the VLAN→VLAN VPN→VPN Config page, enable the VPN mode. 2 Configure the global TPID. Optional. On the VLAN→VLAN VPN→VPN Config page, configure the global TPID basing on the devices connected to the up-link port. 3 Set the VPN up-link port. Required. On the VLAN→VLAN VPN→VPN Config page, specify the desired port to be the VPN up-link port. It's required to set the port connected to the backbone networks to be up-link port. 4 Create VLAN Mapping Required. On the VLAN→VLAN VPN→VLAN Mapping entries. page, configure the VLAN Mapping entries basing on the actual application. 5 Create SP (Service Optional. On the VLAN→802.1Q VLAN page, create the Provider) VLAN. SP VLAN. For the steps of creating VLAN, please refer to 802.1Q VLAN. Configuration Procedure of VLAN Mapping Function: Step Operation 1 Create VLAN entries. 2 Enable VLAN function for port. 3 Create SP Provider) VLAN Description Mapping Required.

GVRP allows the switch to automatically add or remove the VLANs via the dynamic VLAN registration information and propagate the local VLAN registration information to other switches, without having to individually configure each VLAN. GARP GARP provides the mechanism to assist the switch members in LAN to deliver, propagate and register the information among the members. GARP itself does not work as the entity among the devices. The application complied with GARP is called GARP implementation, and GVRP is the implementation of GARP. When GARP is implemented on a port of device, the port is called GARP entity. The information exchange between GARP entities is completed by messages. GARP defines the messages into three types: Join, Leave and LeaveAll. 92
