22 Configuring an Internal
DHCP Server
The Dynamic Host Configuration Protocol (DHCP) offers a framework to provide configuration
information to client interfaces on an IPv4 or IPv6 IP network. DHCP is based on the Bootstrap Protocol
(BOOTP) and provides additional capabilities, such as dynamic allocation of reusable network addresses
and configuration options.
A DHCP server provides dynamic IP addresses on lease for client interfaces on a network. It manages a
pool of IP addresses and information about client configuration parameters. The DHCP server obtains an
IP address request from the client interfaces. After obtaining the requests, the DHCP server assigns an IP
address, a lease period, and other IP configuration parameters, such as the subnet mask and the default
gateway.
This chapter describes how to configure the internal DHCP server on the OmniSwitch.
In This Chapter
This chapter describes configuration of the DHCP server and how to modify the configuration through the
Command Line Interface (CLI). CLI commands are used in the configuration examples; for more details
on the syntax of commands, see the OmniSwitch AOS Release 8 CLI Reference Guide.
