DHCP Configuration Examples

default gateway 10.1.1.1 that resides on the 10.1.x.x subnet. When all the addresses for

‘scope1’ are assigned, the server will start giving out addresses from ‘scope2’ which will

include the default gateway parameter 10.2.1.1 on subnet 10.2.x.x.

Secondary Subnets and Directly-Connected Clients

A directly-connected client is a system that resides on the same physical network as the

DHCP server and does not have to go through a router or relay agent to communicate

with the server. If you configure the DHCP server on the XP to service directly-connected

clients on a secondary subnet, you must configure the secondary subnet using the

interface add ip command. The interface add ip command configures a secondary

address for an interface that was previously created with the interface create ip

command.

The following example shows a simple configuration to support directly-connected

clients on a secondary subnet.

1. Create an interface ‘clients’ with the primary address 10.1.1.1.

2. Assign a secondary address 10.2.1.1 to the interface ‘clients’.

3. Define the network parameters for ‘scope1’ with the default gateway 10.1.1.1.

4. Define the address pool for ‘scope1’.

5. Define the network parameters for ‘scope2’ with the default gateway 10.2.1.1.

6. Define the address pool for ‘scope2’.

interface create ip clients address-mask 10.1.1.1/16 port et.1.1

interface add ip clients address-mask 10.2.1.1/16

dhcp scope1 define parameters address-netmask 10.1.0.0/16 gateway 10.1.1.1 dns-domain

acme.com dns-server 10.1.44.55

dhcp scope1 define pool 10.1.1.10-10.1.1.20

dhcp scope2 define parameters address-netmask 10.2.0.0/16 gateway 10.2.1.1 dns-domain

acme.com dns-server 10.1.77.88

dhcp scope2 define pool 10.2.1.40-10.2.1.50
