CHAPTER 18
DHCP
This chapter shows you how to configure the DHCP feature.
18.1 Overview
DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual
computers to obtain TCP/IP configuration at start-up from a server. You can configure the ES-
4024A as a DHCP server or disable it. When configured as a server, the ES-4024A provides
the TCP/IP configuration for the clients. If you disable the DHCP service, you must have
another DHCP server on your LAN, or else the computer must be manually configured.
18.1.1 DHCP modes
The ES-4024A can be configured as a DHCP server or DHCP relay agent.
• If you configure the ES-4024A as a DHCP server, it will maintain the pool of addresses
and distribute them to your LAN computers.
• If there is an Ethernet device that performs the DHCP server function for your network,
then you can configure the ES-4024A as a DHCP relay agent. When the ES-4024A
receives a request from a computer on your network, it contacts the Ethernet device (the
DHCP server) for the necessary IP information, and then relays the assigned information
back to the computer.
