DHCP
This chapter shows you how to configure the DHCP feature.
29.1 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
switch as a DHCP server or disable it. When configured as a server, the switch 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.
29.1.1 DHCP modes
The switch can be configured as a DHCP server or DHCP relay agent.
• If you configure the switch 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 switch as a DHCP relay agent. When the switch 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.
29.2 DHCP Server Status
Click IP Application , DHCP in the navigation panel. The DHCP Server Status screen
