DHCP overview

The Dynamic Host Configuration Protocol (DHCP) provides a framework to assign configuration
information to network devices.
DHCP uses the client-server model.
A DHCP client can obtain an IP address and other configuration parameters from a DHCP server on
another subnet through a DHCP relay agent. For more information about the DHCP relay agent, see
"Figure 281." You can enable the DHCP client on an interface. For more information about the DHCP
client configuration, see
Figure 281 A typical DHCP application

DHCP address allocation

Allocation mechanisms

DHCP supports the following mechanisms for IP address allocation:
Static allocation—The network administrator assigns an IP address to a client like a WWW server,
•
and DHCP conveys the assigned address to the client.
Automatic allocation—DHCP assigns a permanent IP address to a client.
•
• Dynamic allocation—DHCP assigns an IP address to a client for a limited period of time, which is
called a lease. Most DHCP clients obtain their addresses in this way.
