About Power On Auto Provisioning

When a Cisco MDS Series switch with POAP feature boots and does not find the startup configuration, the
switch enters POAP mode and checks for a USB device (containing the configuration script file) in USB port
1. If it finds a USB device, it checks the device to see if the device also contains the software image files and
the switch configuration file.
If the switch does not find a USB device in USB port 1, or if the USB device does not contain the required
software image files or the switch configuration file, the switch locates a DHCP server and bootstraps itself
with the server's interface IP address, gateway, and DNS server IP addresses. The switch then obtains the IP
address of a TFTP server or the URL of an HTTP server from where it downloads the necessary configuration
files.
