Note that you as the operator have full control of building the script and making sure it has the logic you desire. The switch now reaches out to the TFTP server and downloads the Python file from the TFTP server and executes it. In addition to assigning an IP address to the device, the DHCP server’s response contains the name of a Python(or TCL) script in option 150/66 along with the IP address of a TFTP server to download the script from. The DHCP server receives the request and based on the source mac address, assigns the device an IP address. One of the first things a brand new switch on boot does, is make a DHCP request. Let’s explore the technology and a sample workflow that makes this magic happen. Sound pretty cool? It should be because the switch comes up ready and configured to production standards – all this without any human logging in to the device! With POAP, the brand new switch boots for the first time (or with an empty startup config), get’s an IP address via DHCP, figures out the appropriate OS/image needed to meet requirements, downloads this image, downloads the desired configuration, reboots and comes up with the desired configuration and image. Power On Auto Provisioning – Enabling zero touch provisioning for data center switches. We plan to change that! This particular feature, Power On Auto Provisioning (POAP), is available on all Cisco Nexus switches and empowers data center network engineers to provision brand new switches automatically without ever using a console cable anymore! And now there’s a new POAP learning lab on DevNet to help you up the learning curve quickly. In fact, there has been a feature that helps with bootstrapping devices on NX-OS for years. Thankfully, you don’t have to put up with that when you’re using Cisco Nexus switches. If you were to tell your cloud or server admin friends that in this day and age you have to manually configure every switch as you un-box and deploy them, you’ll probably get expressions that range from sympathy to disdain.
