About Plug and Play
Cisco Prime Infrastructure helps automate the deployment of new devices on the network by obtaining and applying the necessary software image and configuration on a new network device. The Prime Infrastructure uses APIC-EM (Application Policy Infrastructure Controller) call-home and Cisco IOS auto-install (which uses DHCP and TFTP) features thus reducing the time a new device takes to join the network and become functional.
The Plug and Play feature of Prime Infrastructure uses the templates defined in that you can reuse and apply to new devices. You can streamline new device deployment by creating bootstrap templates, which define the necessary initial configurations to enable the device to communicate with Prime Infrastructure. You can specify (and predeploy ) software images and configurations that will be added to the devices in the future.
