3.5 Configuring the DHCP Relay Agent

By using a DHCP relay agent, the DHCP clients on a local area network (LAN) can communicate
with the DHCP servers on other network segments, and obtain IP addresses from them. The
DHCP clients on different network segments can also use one DHCP server. This reduces costs
and achieves centralized device management.

3.5.1 Establishing the Configuration Task

Before configuring the DHCP relay agent, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This helps you complete the
configuration task quickly and accurately.
Applicable Environment
If no DHCP server is configured on the local network, the DHCP relay function can be enabled
on an S9300&S9300E to forward DHCP Request packets to the DHCP servers on other
networks. To ensure that the DHCP clients obtain IP addresses, the DHCP server must use a
global address pool, and no address pool can be configured on the interface connected to the
DHCP relay agent.
