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 <POOL> 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.

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.
