Chapter 5: DHCP Configuration Guide

Configuring DHCP

By default, the DHCP server is not enabled on the SSR. You can selectively enable DHCP service on particular interfaces and not others. To enable DHCP service on an interface, you must first define a DHCP scope. A scope consists of a pool of IP addresses and a set of parameters for a DHCP client. The parameters are used by the client to configure its network environment, for example, the default gateway and DNS domain name.

To configure DHCP on the SSR, you must configure an IP address pool, client parameters, and optional static IP address for a specified scope. Where several subnets are accessed through a single port, you can also define multiple scopes on the same interface and group the scopes together into a “superscope.”

Configuring an IP Address Pool

To define a pool of IP addresses that the DHCP server can assign to a client, enter the following command in Configure mode:

Define pool of IP addresses to be used by clients.

dhcp <scope> define pool <ip-range>

Configuring Client Parameters

You can configure the client parameters shown in the table below.

Table 3. Client Parameters

Parameter	Value

	required and must be defined before any other client
	parameters are specified.)
broadcast	Broadcast address
