Entering the

reservations. Unreserved addresses that are part of the network or on pool ranges are not offered to the
client, and other clients are not served by the pool.
By entering this command, users can configure a group of switches with DHCP pools that share a
common IP subnet and that ignore requests from clients of other switches.
To access DHCP pool configuration mode, enter the
ip dhcp pool
name
global configuration command.
Examples
This example shows how to configure the DHCP pool to allocate only reserved addresses:
Switch#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
ip dhcp pool test1
Switch(dhcp-config)#
reserved-only
You can verify your settings by entering the
show ip dhcp pool
privileged EXEC command.
