VLAN with its VLANID as 10, owning Port 3 and Port 4, and configurethe egress rule of Port 3 as Untag.3 Create VLAN20 Required. On VLAN→802.1Q VLAN→VLAN Config page, create aVLAN with its VLANID as 20, owning Port 3 and Port 5, and configurethe egress rule of Port 3 as Untag.4 Create ProtocolTemplateRequired. On VLAN→Protocol VLAN→Protocol Template page,configure the protocol template practically. E.g. the Ether Type of IPnetwork packets is 0800 and that of AppleTalk network packets is 809B.5 Port Enable Required. On the VLAN→Protocol VLAN→Port Enable page, selectand enable Port 3, Port 4 and Port 5 for Protocol VLAN feature.6 Create ProtocolVLAN 107 Create ProtocolVLAN 20On VLAN→Protocol VLAN→Protocol VLAN page, create protocolVLAN 10 with Protocol as IP.On VLAN→Protocol VLAN→Protocol VLAN page, create protocolVLAN 20 with Protocol as AppleTalk.6.5 GVRPGVRP (GARP VLAN Registration Protocol) is an implementation of GARP (generic attributeregistration protocol). GVRP allows the switch to automatically add or remove the VLANs via thedynamic VLAN registration information and propagate the local VLAN registration information toother switches, without having to individually configure each VLAN.‣ GARPGARP provides the mechanism to assist the switch members in LAN to deliver, propagate andregister the information among the members. GARP itself does not work as the entity among thedevices. The application complied with GARP is called GARP implementation, and GVRP is theimplementation of GARP. When GARP is implemented on a port of device, the port is calledGARP entity.The information exchange between GARP entities is completed by messages. GARP defines themessages into three types: Join, Leave and LeaveAll. Join Message: When a GARP entity expects other switches to register certain attributeinformation of its own, it sends out a Join message. And when receiving the Join messagefrom the other entity or configuring some attributes statically, the device also sends out a Joinmessage in order to be registered by the other GARP entities. Leave Message: When a GARP entity expects other switches to deregister certain attributeinformation of its own, it sends out a Leave message. And when receiving the Leave messagefrom the other entity or deregistering some attributes statically, the device also sends out aLeave message. LeaveAll Message: Once a GARP entity starts up, it starts the LeaveAll timer. After the timertimes out, the GARP entity sends out a LeaveAll message. LeaveAll message is to deregisterall the attribute information so as to enable the other GARP entities to re-register attributeinformation of their own.Through message exchange, all the attribute information to be registered can be propagated to allthe switches in the same switched network.The interval of GARP messages is controlled by timers. GARP defines the following timers:65
