Table 25. DHCP Server Responsibilities DHCP Server Responsibility Address Storage and Management Configuration Parameter Storage and Management Lease Management Responding To Client Requests Providing Administration Services NOTE: DHCP server is not supported on VLT. Description 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. 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. 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. DHCP servers respond to different types of requests from clients, primarily, granting, renewing, and terminating leases. DHCP servers include functionality that allows an administrator to implement policies that govern how DHCP performs its other tasks. Configuring 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. An address pool is a range of IP addresses that the DHCP server may assign. The subnet number indexes the address pools. To create an address pool, follow these steps. 1 Access the DHCP server CLI context. CONFIGURATION mode ip dhcp server 2 Create an address pool and give it a name. DHCP mode pool name 3 Specify the range of IP addresses from which the DHCP server may assign addresses. DHCP mode network network/prefix-length • network: the subnet address. • prefix-length: specifies the number of bits used for the network portion of the address you specify. The prefix-length range is from 17 to 31. 4 Display the current pool configuration. DHCP mode show config Dynamic Host Configuration Protocol (DHCP) 332
