Configuration Tasks To configure DHCP, an administrator must first set up a DHCP server and provide it with configuration parameters and policy information including IP address ranges, lease length specifications, and configuration data that DHCP hosts need. Configuring the Dell system to be a DHCP server is a three-step process: 1. Configuring the Server for Automatic Address Allocation 2. Specifying a Default Gateway 3. Enable the system to be a DHCP server (no disable command). Related Configuration Tasks • Configure a Method of Hostname Resolution • Creating Manual Binding Entries • Debugging the DHCP Server • Using DHCP Clear Commands 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 configured pools. DHCP mode excluded-address 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.
