Cisco ACI Guide for Humans, Part 2: Upgrade Cisco ACI

First time we “unpack” ACI, we will find a certain number of potential Spine and potential Leaf switches, and hopefully 3 (or 5) APIC Controllers. We will rack the entire fabric, interconnect every Spine to every Leaf with a single 40G cable, and connect every APIC to 2 Leaf Switches. We would power on the devices, and before we even start configuring the APIC Cluster, we need to console to each Switch and verify if its running ACI mode or a NX-OS mode by executing the “show version” command. These are the details of the Fabric we used in our Lab:
