Syntax Description

Command Modes

DHCP pool configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 12.0(1)T.

If the mask and prefix length are unspecified, DHCP examines its address pools. If no mask is found in the pool database, the Class A, B, or C natural mask is used. This command is valid for manual bindings only.

There is no limit on the number of manual bindings but you can only configure one manual binding per host pool.

Examples

The following example specifies 10.12.1.99 as the client’s IP address and 255.255.248.0 as the subnet mask:

host 10.12.1.99 255.255.248.0
