Discovery / Using arpwatch tables to import IP's to Nedi
« on: August 12, 2019, 06:12:03 PM »
Hello all, I have a fancy new Palo Alto firewall and I have moved some VLAN's over to it. I ran into trouble with Nedi which ultimately I figured out was because Palo Alto doesn't provide MAC/ARP with SNMP (boooo!!!).

I am attempting to pull a fast one on Nedi by using Arpwatch. I wrote a shell script that connects to the Palo Alto, pulls down an ARP list, formats it into a standard Arpwatch file, and then waits for Nedi to come collect it.

When I run Nedi manually, it *seems* to be collecting the data and ingesting it ...

BUT, then if I search my Nedi database for any Nodes or Devices with these IP addresses - I come up empty. If I search for the MAC address, I can find it. But the IP is blank. Is there something else that I need to do to force Nedi to connect these two pieces of information?
