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:
