Dear Rob.hoc,
Thank you for the reply. I would accept if it misses a few. What I am referring is it is missing all nodes of a vlan. I have 6 such vlans and I am unable to get all the nodes into my map. In other words this utility is useless for me. We have a standalone product from solarwinds, the “Lansurveyor”. It does a perfect job for me, and it is one of the reason to go for NPM too.
