This chapter shows you how to configure the DHCP feature.
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
a DHCP relay agent. When configured as a server, the Switch provides the TCP/IP configuration for the
clients. If you configure the Switch as a relay agent, then the Switch forwards DHCP requests to DHCP
server on your network. If you do not configure the Switch as a DHCP server or relay agent then you must
have a DHCP server in the broadcast domain of the client computers or else the client computers must
be configured manually.
