132 CHAPTER 10: DHCP SERVER CONFIGURATION
Customizing DHCP
Service
With the evolution of DHCP, new options are constantly coming into being. You can
add the new options as the properties of DHCP servers by performing the following
configuration.
Configuring Gateway
Addresses for DHCP
Clients
Gateways are necessary for DHCP clients to access servers/hosts outside the current
network segment. After you configure gateway addresses on a DHCP server, the
DHPC server provides the gateway addresses to DHCP clients as well while assigning
IP addresses to them.
You can configure gateway addresses for address pools on a DHCP server. Currently,
you can configure up to eight gateway addresses for a DHCP address pool.
Interface Address Pool-based DHCP Server Configuration
This section contains configuration information for Interface Address Pool-Based
DHCP Server
Configuration Overview An interface address pool is created when the interface is assigned a valid unicast IP
address and you execute the dhcp select interface command in interface view. The IP
addresses contained in it belong to the network segment where the interface resides
in and are available to the interface only.
You can perform certain configurations for DHCP address pools of an interface or
multiple interfaces within specified interface ranges. Configuring for multiple
