Configuration Procedure: Step Operation 1 Set the link type for port. 2 Create VLAN. 3 Create VLAN interface. 4 Enable DHCP Server. 5 Configure Excluded IP Address. 6 Configure IP Pool. 7 Bind IP Manually Description Required. On the VLAN→802.1Q VLAN→Port Config page, set the link type for the port basing on its connected device. Required. On the VLAN→802.1Q VLAN→VLAN Config page, click the Create button to create a VLAN. Enter the VLAN ID and the description for the VLAN. Meanwhile, specify its member ports. Required. On the Routing→Static Routing→Static Routing Config page, create the interface IP address of the VLAN. Required. On the Routing→DHCP Server→DHCP Server page, enable the DHCP Server function. Optional. On the Routing→DHCP Server→DHCP Server page, configure the Excluded IP Address which can not be assigned by the switch. Required. On the Routing→DHCP Server→Pool Setting page, configure the parameters of IP Pool, including Mask, lease time, gateway and DNS address. Optional. On the Routing→DHCP Server→Manual Binding page, you can specify the IP address for specific clients. 10.5 DHCP Relay  Application Environment of DHCP Relay In DHCP model, DHCP clients broadcast its DHCP request, so the DHCP sever and clients must be on the same subnet, which require the DHCP server is available in every subnet. It is costly to build so much DHCP Server. DHCP relay agent solves the problem. Via a relay agent, DHCP clients request an IP address from the DHCP server in another subnet, and DHCP clients in different subnets can share the same DHCP server in the internet. 150
