Information About PowerOn Auto Provisioning
PowerOn Auto Provisioning (POAP) automates the process of upgrading software images and installing
configuration files on Cisco Nexus switches that are being deployed in the network for the first time.
When a Cisco Nexus Series switch with the 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. If it finds
one, it checks that device to see if it also contains the software image files and the switch configuration file.
If the switch does not find a USB device, or if the USB device does not contain the needed image files or
switch configuration file, the switch also locates a DHCP server and bootstraps itself with its 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 which it downloads the necessary configuration files.
The DHCP information is used only during the POAP process if any configuration files are unavailable
on the USB device.
