17.1 About DHCP

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-4024 as a DHCP server or disable it.
When configured as a server, the ES-4024 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.
17.1.1 DHCP modes
The ES-4024 can be configured as a DHCP server or DHCP relay agent.
•
If you configure the ES-4024 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-4024 as a DHCP relay agent. When the ES-4024 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.
