Privileged EXEC 

Entering the reserved-only command restricts assignments from the DHCP pool to preconfigured 
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.

This example shows how to configure the DHCP pool to allocate only reserved addresses:

Switch# config t

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.
