Initial Setup

How to Install Cumulus Linux on a Switch

The switch when powered up would use DHCP to get an IP address, and then attempt to discover the Network Operating System (NOS) over a network using Ethernet 0 which is the management port of the switch. At the most basic level, you can plug in your laptop into Ethernet0 (Eth0) of the switch and if you have a litte web server running on your laptop, you could an image into a directory and the switch would then download the image into the switch.

This method is not going to scale if you have 100's of switches To do this, you would use OOB (out-of-band) managemnet network to configure your switches. The switches Eth0 port would connect to a TOR (top-of-rack) switch and using DHCP which would provide access to a Web Server hosting the Cumulus Network Image.
