Configure the System to be a DHCP Server

Configuring the system to be a DHCP server is supported only on the S6000 platform.

A DHCP server is a network device that has been programmed to provide network configuration

parameters to clients upon request. Servers typically serve many clients, making host management much

more organized and efficient.

The following table lists the key responsibilities of DHCP servers.

Table 18. DHCP Server Responsibilities

DHCP Server Responsibility Description

Address Storage and Management DHCP servers are the owners of the addresses

used by DHCP clients.The server stores the

addresses and manages their use, keeping track of

which addresses have been allocated and which

are still available.

Configuration Parameter Storage and Management DHCP servers also store and maintain other

parameters that are sent to clients when

requested. These parameters specify in detail how

a client is to operate.

Lease Management DHCP servers use leases to allocate addresses to

clients for a limited time. The DHCP server

maintains information about each of the leases,

including lease length.

Responding To Client Requests DHCP servers respond to different types of

requests from clients, primarily, granting, renewing,

and terminating leases.

Providing Administration Services DHCP servers include functionality that allows an

administrator to implement policies that govern

how DHCP performs its other tasks.

Configuring the Server for Automatic Address Allocation

Automatic address allocation is an address assignment method by which the DHCP server leases an IP

address to a client from a pool of available addresses.

An address pool is a range of IP addresses that the DHCP server may assign. The subnet number indexes

the address pools.

To create an address pool, follow these steps.

1. Access the DHCP server CLI context.

CONFIGURATION mode

ip dhcp server

2. Create an address pool and give it a name.
