3.3.1 DHCP service
DHCP adopts Client/Server communication mode. Client sends configuration request to Server
which feeds back corresponding configuration information, including distributed IP address to the
Client to achieve the dynamic configuration of IP address and other information.
The duty of DHCP Server is to distribute IP address when Workstation logs on and ensure
each workstation is supplied with different IP address. DHCP Server has simplified some
network management tasks requiring manual operations before to the largest extent.
As DHCP Client, the device receives the IP address distributed by DHCP server after logging
in the DHCP server, so the Ethernet interface of the device needs to be configured into an
automatic mode.
To enable the DHCP server, find the navigation tree, select Services >> DHCP Service, then enter
“DHCP Service” page.
