The key responsibilities of DHCP servers are: 1. Address Storage and Management: DHCP servers are the owners of the addresses used by DHCP clients.The server stores the addresses and manages their use, keeping track of which addresses have been allocated and which are still available. 2. Configuration Parameter Storage and Management: DHCP servers also store and maintain other parameters that are sent to clients when requested. These parameters specify in detail how a client is to operate. 3. Lease Management: DHCP servers use leases to allocate addresses to clients for a limited time. The DHCP server maintains information about each of the leases, including lease length. 4. Responding To Client Requests: DHCP servers respond to different types of requests from clients, primarily, granting, renewing, and terminating leases. 5. Providing Administration Services: The DHCP server includes functionality that allows an administrator to implement policies that govern how DHCP performs its other tasks. 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 Force10 system to be a DHCP server is a 3-step process: 1. Configure the Server for Automatic Address Allocation 2. Specify a Default Gateway 3. Enable DHCP Server Related Configuration Tasks • Configure a Method of Hostname Resolution • Create Manual Binding Entries • DHCP Clear Commands Configure the Server for Automatic Address Allocation Automatic Address Allocation is an address assignment method, by which the DHCP server leases an IP address to a client from a pool of available addresses. c s This feature is available on and (S25/S50) platforms only.
