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:
