legal clients of the DHCP Server group.

4.4 DHCP Relay Configuration Example

I. Networking requirements
The segment address for DHCP Client is 10.110.0.0, which is connected to a port in the
VLAN2 on the switch. The IP address of DHCP Server is 202.38.1.2. The DHCP
packets should be forwarded via the switch with DHCP Relay enabled. DHCP Client
can get IP address and other configuration information from DHCP Server.

III. Configuration procedure
# Configure the group number of DHCP Server as 1 and the IP address as 202.38.1.2.
[Quidway] dhcp-server 1 ip 202.38.1.2
# Associate the VLAN interface 2 with DHCP Server group 1.
[Quidway] interface vlan 2
[Quidway-Vlan-interface2] dhcp-server 1
# Configure the IP address of the VLAN interface 2, which must be in the same
segment as DCHP Client.
[Quidway-Vlan-interface2] ip address 10.110.1.1 255.255.0.0
To allocate IP address successfully for DHCP Client, you need to make necessary
configuration on DHCP Server, which varies, depending on device type.
