DHCP relay agent configuration

NOTE:
The DHCP relay agent configuration is supported only on VLAN interfaces.

Introduction to DHCP relay agent

Application environment

Via a relay agent, DHCP clients can communicate with a DHCP server on another subnet to obtain
configuration parameters. DHCP clients on different subnets can contact the same DHCP server rather
than having a DHCP server on each subnet. This centralizes management and reduces cost.

Fundamentals

Figure 26 shows a typical application of the DHCP relay agent.

The DHCP server and client interact with each other in the same way with or without a replay agent (see
the chapter ―DHCP overview‖).
