Configuring DHCP Services
Using Dynamic Host Configuration Protocol (DHCP), you can enable clients to
acquire permanent IP configuration parameters and a temporary IP address. Refer
to this chapter for
• An overview of the DHCP protocol (see pa
ge 4-1)
• Features of the Bay Networks implementation of DHCP (see pa

• Instructions for enabling DHCP services (see pa

DHCP Overview
DHCP enables clients to obtain an IP address for a fixed length of time (a lease
period) from remote servers (DHCP servers). The lease period can range from
1 minute to 99 years. When the lease period expires, the server can assign the IP
address to another client on the network. DHCP also enables clients to acquire the
IP configuration parameters they need to communicate on a network.
DHCP uses the BOOTP relay agent to forward packets. The BOOTP relay agent
uses the same criteria and methods for forwarding both DHCP and BOOTP
packets. Refer to “BOO
TP Relay Agent Overview” in Chapter 3 for information
about the packet relay process.
