• Load balancing algorithm is effective only for outgoing traffic if the data stream is not well shared by each link you can change the algorithm of the outgoing interface 144
• Please properly choose the load balancing algorithm to avoid data stream transferring only on one physical link for example switch a receives packets from several hosts and forwards them to the server with the fixed mac address and ip address you can set the algorithm as src mac src ip to allow switch a to determine the forwarding port based on the source mac addresses and source ip addresses of the received packets 144

• Overview 288
• 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 applied 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 288
• 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 288

• 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 294
• Network requirements 294
• 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 294
• To configure dynamic vlan creation on other switches set the registration mode of the corresponding ports as normal to allow dynamic registration and de registration of vlans 294
• To reduce manual configuration and maintenance workload gvrp can be enabled to implement dynamic vlan registration and update on the switches 294

• Overview 388
• As the above figure shows the oam entity on switch a is in active mode and that on switch b is in passive mode switch a initiates an oam connection by sending an information oampdu switch b compares the oam information in the received oampdu with its own and sends back an information oampdu to switch a if the oam information of the two entities matches an oam connection will be established after that the two oam entities will exchange information oampdus periodically to keep the oam connection valid 389
• Link monitoring 389
• Link monitoring is for monitoring link performance under various circumstances when problems are detected on the link the oam entity will send its remote peer the event notification oampdus to report link events 389

• The switch supports the following oam features link monitoring remote failure indication rfi and remote loopback 389

• Dhcp relay 571
• 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 20 572
• Dhcp vlan relay 572
• Dhcp vlan relay allows clients in different vlans to obtain ip addresses from the dhcp server using a single agent interface ip address 572
• In dhcp interface relay to assign ip addresses to clients in different vlans you need to create a layer 3 interface for each vlan to ensure the reachability 572
• In dhcp vlan relay you can simply specify a layer 3 interface as default agent interface for all vlans the swith will fill this default agent interface s ip address in the relay agent ip address field of the dhcp packets from all vlans 572
• Dhcp server configuration 574

• Click create 578
