We have the Cisco SNT tool on our network which polls devices and get chassis information like the chassis manager in Spectrum. I was asked to see if I can export the contents ; chassis and all sub-components, including line cards sfp's etc., so we could compare my findings with Cisco. There is no way to do this without manually doing each device one at at time.... I'm not doing that for 20,0000 devices.
What I would like to see is the export function for chassis manager and maybe a radio button < include all sub-components for each device> added to Spectrum
