    UDT - what goes on behind the curtains

    Donald_Francis

      Can someone from SolarWinds confirm what UDT does when it polls for info?  I am trying to figure where the breakdown is so I can possibly solve my issues where I am getting very hit and miss results.

      I have some switches that do not get any info , some that only show MAC's and a few that work fully.

       

      Is this the way it is?

       

      Pull Mac table -> find nearest layer 3 and pull ARP cache (via cdp?)-> Do reverse DNS lookups on IPs -> Correlate all the data

       

      My guess is maybe the ones where I get MACs only the chassis is performing L3 and the switch ARP does not get pulled.

      The ones where I get nothing, well I have no clue about those yet but it must be for the same reason as its all my 6500's so far and then my Nexus 5k's.
