• Protocol vlan is a technology that divides vlans based on the network layer protocol with the protocol vlan rule configured on the basis of the existing 802 q vlan the switch can analyze specific fields of received packets encapsulate the packets in specific formats and forward the packets with different protocols to the corresponding vlans since different applications and services use different protocols network administrators can use protocol vlan to manage the network based on specific applications and services 187

• A company uses both ipv4 and ipv6 hosts and these hosts access the ipv4 network and ipv6 network respectively via different routers it is required that ipv4 packets are forwarded to the ipv4 network ipv6 packets are forwarded to the ipv6 network and other packets are dropped 195
• Configuration example 195

• The figure below shows the network topology the ipv4 host belongs to vlan 10 the ipv6 host belongs to vlan 20 and these hosts access the network via switch 1 switch 2 is connected to two routers to access the ipv4 network and ipv6 network respectively the routers belong to vlan 10 and vlan 20 respectively 195
• You can configure protocol vlan on port 1 0 1 of switch 2 to meet this requirement when this port receives packets switch 2 will forward them to the corresponding vlans according to their protocol types the overview of the configuration on switch 2 is as follows 195

• Configuring gvrp 207
• Part 9 207
• Gvrp garp vlan registration protocol is a garp generic attribute registration protocol application that allows registration and deregistration of vlan attribute values and dynamic vlan creation 208
• Overview 208
• The configuration may seem easy in this situation however for a larger or more complex network such manual configuration would be time costing and fallible gvrp can be used to implement dynamic vlan configuration with gvrp the switch can exchange vlan configuration information with the adjacent gvrp switches and dynamically create and manage the vlans this reduces vlan configuration workload and ensures correct vlan configuration 208
• Without gvrp operating configuring the same vlan on a network would require manual configuration on each device as shown in figure 1 1 switch a b and c are connected through trunk ports vlan 10 is configured on switch a and vlan 1 is configured on switch b and switch c switch c can receive messages sent from switch a in vlan 10 only when the network administrator has manually created vlan 10 on switch b and switch c 208

• Department a and department b of a company are connected using switches offices of one department are distributed on different floors as shown in figure 3 1 the network topology is complicated configuration of the same vlan on different switches is required so that computers in the same department can communicate with each other 214
• Network requirements 214
• The two departments are in separate vlans to make sure the switches only dynamically create vlan of their own department you need to set the registration mode for ports on switch 1 to switch 4 as fixed to prevents dynamic registration and deregistration of vlans and allow the port to transmit only the static vlan registration information 214
• To configure dynamic vlan creation on other switches set the registration mode of the corresponding ports as normal to allow dynamic registration and deregistration of vlans 214
• To reduce manual configuration and maintenance workload gvrp can be enabled to implement dynamic vlan registration and update on the switches 214

• A member port is a port on snooping switch that is connecting to the host 226
• A router port is a port on snooping switch that is connecting to the igmp querier 226
• A snooping switch indicates a switch with igmp snooping enabled the switch maintains a multicast forwarding table by snooping on the igmp transmissions between the host and the querier with the multicast forwarding table the switch can forward multicast data only to the ports that are in the corresponding multicast group so as to constrain the flooding of multicast data in the layer 2 network 226
• An igmp querier is a multicast router a router or a layer 3 switch that sends query messages to maintain a list of multicast group memberships for each attached network and a timer for each membership 226
• Demonstrated as below 226
• Igmp querier 226
• Member port 226

• To implement this requirement you can configure the default gateway of host a as 10 24 the default gateway of host b as 10 24 and configure ipv4 static routes on switch a and switch b so that hosts on different network segments can communicate with each other 429

• As the following figure shows no ip addresses are assigned to vlan 10 and vlan 20 but a default relay agent interface is configured with the ip address 192 68 24 the switch uses ip address of the default agent interface 192 68 24 to apply for ip addresses for clients in both vlan 10 and vlan 20 as a result the dhcp server will assign ip addresses on 192 68 24 the same subnet with the ip address of the default agent interface to clients in both vlan 10 and vlan 20 437
• Dhcp l2 relay 437
• Unlike dhcp relay dhcp l2 relay is used in the situation that the dhcp server and client are in the same vlan in dhcp l2 relay in addition to normally assigning ip addresses to clients from the dhcp server the switch can record the location information of the dhcp client using option 82 the switch can add option 82 to the dhcp request packet and then transmit the packet to the dhcp server the dhcp server which supports option 82 can set the distribution policy of ip addresses and the other parameters providing a more flexible address distribution way 437

• Local proxy arp is similar with proxy arp as shown below two hosts are in the same vlan and connected to vlan interface 1 but port 1 0 1 and port 1 0 2 are isolated on layer 2 in this case both of the hosts cannot receive each other s arp request so they cannot communicate with each other because they cannot learn each other s mac address using arp packets 475
• To solve this problem you can enable local proxy arp on the layer 3 interface and the interface will respond the arp request sender with its own mac address after that the arp request sender sends packets to the layer 3 interface and the interface forwards the packets to the intended device 475

• A mib is a collection of managed objects that is organized hierarchically the objects define the attributes of the managed device including the names status access rights and data types each object can be addressed through an object identifier oid 805
• Also tp link switches support the following public mibs 805
• As the following figure shows the mib hierarchy can be depicted as a tree with a nameless root the levels of which are assigned by different organizations the top level mib object ids belong to different standards organizations while lower level object ids are allocated by associated organizations vendors can define private branches that include managed objects for their own products 805

• Tp link switches provide private mibs that can be identified by the oid 1 1863 the mib file can be found on the provided cd or the download center of our official website http www tp link com en download center html 805
• An snmp engine can be uniquely identified by an engine id within an administrative domain since there is a one to one association between snmp engines and snmp entities we can also use the engine id to uniquely and unambiguously identify the snmp entity within that administrative domain 806
• An snmp engine is a part of the snmp entity every snmp entity has one and only one engine an snmp engine provides services for ending and receiving messages authenticating and encrypting messages and controlling access to managed objects 806
• An snmp entity is a device running the snmp protocol both the snmp manager and snmp agent are snmp entities 806
