PowerOn Auto Provisioning (POAP) is a feature that automates the process of upgrading software images and installing configuration files on Cisco devices that are deployed in a network for the first time. It is particularly useful for scenarios where multiple switches need to be provisioned without manual intervention. When a switch with POAP boots up and does not find a startup configuration, it enters the POAP mode, locates a DHCP server, and bootstraps itself with its interface IP address, gateway, and DNS server IP address. It then obtains the IP address or URL of a TFTP server and downloads the necessary scripts and software images to configure the device12.
