DHCP Server Responsibility Description
Responding To Client Requests DHCP servers respond to dierent types of requests from clients,
primarily, granting, renewing, and terminating leases.
Providing Administration Services DHCP servers include functionality that allows an administrator to
implement policies that govern how DHCP performs its other tasks.
Conguration Tasks
To congure DHCP, an administrator must rst set up a DHCP server and provide it with conguration parameters and policy information
including IP address ranges, lease length specications, and conguration data that DHCP hosts need.
Conguring the Dell system to be a DHCP server is a three-step process:
1 Conguring the Server for Automatic Address Allocation
2 Specifying a Default Gateway
3 Enabling the DHCP Server

• Creating Manual Binding Entries
• Debugging the DHCP Server
• Using DHCP Clear Commands
Conguring 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 <POOL> mode
network network/prefix-length
• network: the subnet address.
• prefix-length: species the number of bits used for the network portion of the address you specify.
The prex-length range is from 17 to 31.
