Step 4 Operation Configure the IP address pool 5 Configure the reserved addresses 6 Manually binding IP addresses Note Required. On page Routing→DHCP Server→Pool Setting, configure IP address pool parameters for each VLAN interface. Take VLAN10 as an example, configure its Network Address as 192.168.10.0, Subnet Mask as 255.255.255.0, Default gateway as 192.168.10.1 (the IP address of the VLAN interface), DNS Server as 160.20.30.2, and customize the Pool Name and Lease Time. Required. On page Routing→DHCP Server→DHCP Server, under the Excluded IP Address, configure reserved IP addresses for the fixed computers in each VLAN. Optional. On page Routing→ DHCP Server→Manual Binding, bind specified ip addresses to the specific clients.  Configure Access Switch Step 1 2 3 Operation Note Enable DHCP Relay. Required. On the Routing→DHCP Server→Global Config page, enable the DHCP Server function, and the DHCP Relay function will be enabled at the same time. Configure Option Optional. On the Routing→DHCP Relay→Global Config page, 82 support. configure the Option 82 parameters. Configure DHCP Required. On the Routing→DHCP Relay→DHCP Server page, Server. specify the DHCP Server with the IP address of the central switch. 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.  Details of DHCP Relay on T2700G-28TQ A typical application of T2700G-28TQ working at DHCP Relay function is shown below. It can be altered to meet the network requirement. 161

the DHCP Server function, and the DHCP Relay function
will be enabled at the same time.
2
Configure
Option
82 support.
Optional. On the

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.
Details of DHCP Relay on T2700G-28TQ
A typical application of T2700G-28TQ working at DHCP Relay function is shown below. It can be
altered to meet the network requirement.
