Configuring a DHCP Client (CLI Procedure)
A Dynamic Host Configuration Protocol (DHCP) server can provide many valuable TCP/IP
network services. DHCP can dynamically allocate IP parameters, such as an IP address,
to clients, and it can also deliver software upgrades to clients.
DHCP configuration consists of two components, configuration of DHCP clients and
configuration of a DHCP server. Client configuration determines how clients send a
message requesting an IP address, whereas a DHCP server configuration enables the
server to send an IP address configuration back to the client. This topic describes
configuring a DHCP client. For directions for configuring a DHCP server, see Configuring
a DHCP Server on Switches (CLI Procedure) or “Configuring a DHCP Server on Switches
(CLI Procedure)” on page 14.
