Conguration Tasks
To congure DHCP, an administrator must rst set up a DHCP server and provide it with conguration parameters and policy information
including IP address ranges, lease length specications, and conguration data that DHCP hosts need.
Conguring the Dell system to be a DHCP server is a three-step process:
1 Conguring the Server for Automatic Address Allocation
2 Specifying a Default Gateway

Excluding Addresses from the Address Pool
The DHCP server assumes that all IP addresses in a DHCP address pool are available for assigning to DHCP clients.
You must specify the IP address that the DHCP server should not assign to clients.
To exclude an address, follow this step.
• Exclude an address range from DHCP assignment. The exclusion applies to all congured pools.

Specifying an Address Lease Time
To specify an address lease time, use the following command.
• Specify an address lease time for the addresses in a pool.
DHCP <POOL>
lease {days [hours] [minutes] | infinite}
The default is 24 hours.
Specifying a Default Gateway
The IP address of the default router should be on the same subnet as the client.
To specify a default gateway, follow this step.
• Specify default gateway(s) for the clients on the subnet, in order of preference.
