Yes, I had a brain glitch and was confusing ARP table with the MAC address table.
I thought wouldn't that be cool just to see which MAC address were learned on which ports, but I understand that in many networks there would just be too many MAC addresses to keep track of.

Is this port by chance running a lot of traffic? As I understood from a conversation on IRC, the realtime poller is (currently) using regular 32bit counters instead of the 64bit high precision ones. You may be overflowing the counter confusing the script. Not much to do except try to patch it so it uses HC counters; but it needs some sort of fallback for devices that only have the 32bit ones :)
- The Arp Table output for my ports are blank. Does this feature work for you? If so, does anyone have this working with Arista switches?
Are you maybe confusing ARP table with Bridge MAC table?
I don't know if Arista exposes their layer 3 mac table. Fenestro on IRC may know :)
