• To meet the requirement that all the traffic from vlan 100 and vlan 200 need to be transmitted through different isp vlans users can configure flexible vlan vpn on switch 1 and switch 2 to map vlan 100 to vlan 1050 and vlan 200 to vlan 1060 so packets from vlan 100 and vlan 200 will be transmitted through vlan 1050 and vlan 1060 respectively 255
• Using the gui 255
• Port config to set the pvid as 1050 for port 1 0 2 and leave the default vaule 1 for port 1 0 1 259
• Using the cli 264

• Chapters 268
• Configuring gvrp 268
• Part 11 268
• 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 269
• Overview 269
• 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 269
• 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 269
• Configuration guidelines 270

• Configuration scheme 275
• 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 275
• Network requirements 275
• The following sections provide configuration procedure in two ways using the gui and using the cli 275
• 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 275
• 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 275
• To reduce manual configuration and maintenance workload gvrp can be enabled to implement dynamic vlan registration and update on the switches 275
• When configuring gvrp please note the following 275
• Using the gui 276
• Using the cli 280
• Verify the configuration 282
• Appendix default parameters 284

• Configuring layer 2 multicast 285
• Part 12 285
• Layer 2 multicast 286
• Overview 286
• A member port is a port on snooping switch that is connecting to the host 287
• A router port is a port on snooping switch that is connecting to the igmp querier 287
• 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 287
• 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 287
• Demonstrated as below 287
• Igmp querier 287
• Member port 287
• Normally only one device acts as querier per physical network if there are more than one multicast router in the network a querier election process will be implemented to determine which one acts as the querier 287

• Also tp link switches support the following public mibs 854
• 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 854

• 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 855
• 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 855
• An snmp entity is a device running the snmp protocol both the snmp manager and snmp agent are snmp entities 855
