Hi,
In most ways, discovery is optional -- HOWEVER, there is one exception
to that.
When a system sends an initial "I'm here, please configure me" packet,
that packet contains netconfig discovery data - giving the local network
topology. As a result, this discovery packet is mandatory.
Below is some annotated sample output - optional things are shown with
'*' at the end of the deescription.
{
"discovertype": "netconfig", *# /Type of discovery - cannot change/*
"description": "IP Network Configuration", /*# Human description*/
"source": "netconfig", */# Name of script performing the
