• Vlan is generally divided by ports it is a common way of division but isn t suitable for those networks that require frequent topology changes with the popularity of mobile office at different times a terminal device may access the network via different ports for example a terminal device that accessed the switch via port 1 last time may change to port 2 this time if port 1 and port 2 belong to different vlans the user has to re configure the switch to access the original vlan using mac vlan can free the user from such a problem it divides vlans based on the mac addresses of terminal devices in this way terminal devices always belong to their mac vlans even when their access ports change 186

• 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
• 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 226

• Overview 446
• Supported features 446
• 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 20 448
• Dhcp l2 relay 448
• 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 448

• Local proxy arp 497
• 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 497
• 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 497

• Also tp link switches support the following public mibs 850
• 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 850

• 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 851
• 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 851
• An snmp entity is a device running the snmp protocol both the snmp manager and snmp agent are snmp entities 851
