10.4.6 Application Example for DHCP Server and Relay  Network Requirements  Every building in the campus belongs to separate VLANs with different network segments.  The access points in each building are divided into two parts. One part is the fixed computers with static IP addresses in the teachers' offices; the other is the classroom, in which most clients are laptops with dynamic IP addresses obtained from the DHCP server.  DNS Server is in VLAN 1and its IP address is 160.20.30.2.  Network Diagram Use T2700G-28TQ as the central switch and enable its DHCP server function to allocate IP addresses to clients in the network. Enable the DHCP relay function on each access switch in VLAN 10, 20 and 30. For details about DHCP relay, please refer to 10.5 DHCP Relay.  Configuration Procedure  Configure Central Switch Step Operation Note 1 Create VLAN Required. On page VLAN→802.1Q VLAN→VLAN Config, create VLAN10, VLAN20 and VLAN30, and configure their ports. 2 Create VLAN interface Required. On page Routing→Interface→Interface Config, configure VLAN interface 192.168.10.1/24 for VLAN10, 192.168.20.1/24 for VLAN20, and 192.168.30.1 for VLAN30. 3 Enable DHCP Server Required. On page Routing→DHCP Server→DHCP Server, enable DHCP Server function under the Global Config. 160

10.4.6 Application Example for DHCP Server and Relay
Network Requirements
Every building in the campus belongs to separate VLANs with different network segments.
The access points in each building are divided into two parts. One part is the fixed computers
with static IP addresses in the teachers’ offices; the other is the classroom, in which most
clients are laptops with dynamic IP addresses obtained from the DHCP server.
DNS Server is in VLAN 1and its IP address is 160.20.30.2.
Network Diagram
Use T2700G-28TQ as the central switch and enable its DHCP server function to allocate IP
addresses to clients in the network. Enable the DHCP relay function on each access switch in
VLAN 10, 20 and 30. For details about DHCP relay, please refer to
