Inconsistent Packet Loss

We are having packet loss problems (along with high ping times) at a tower. I've been working the problem for awhile and cannot find a solution. Our monitoring system shows the problem starting at the Netonix WS-12-250-DC. But I see no problems on the switch. I've upgraded to firmware 1.5.0 (board rev F). Port isolation is on for all ports except the backhaul and on-site access router. STP is disabled. I also upgraded the backhaul (Ignitenet ML-60-35) firmware. The Netonix and backhaul are on the same network segment.
- Pings of the wisp switch
- Traffic to the tower
- Backhaul radio pings
Any suggestions on what to try next to figure this out?

Look at each ports statistics looking for excessive pause frames or errors.
Try disabling Flow Control on all ports.

I should have thought about flow control...
These stats are what you were expecting?
- Netonix stats from backhaul port (Metrolink)
What is the Rx Filtered?
Thanks for your help!

Yes your Tx Pause Frames are VERY HIGH, I would disable Flow Control but find out why you are having these Pause Frames, where is the bottleneck.
As far as Rx Filter:

Turning off flow control fixed the problem. Thanks for your help!
