WISP with Port flapping issues

[sandfox007]

Have three Netonix switches in a row [b]within this arm of our wireless network. First WS-26-500-DC at the POP a WS-12-250-DC 5 miles away at the first tower and a WS-12-250-AC 8 miles away. Firmware either 1.5.5 or 1.5.6, Sites have been operational since spring of 2017. Clients have been complaining of interruptions in service be they streaming or zoom meetings or general internet activities. I have seen the interruptions but have no explanation. Just replaced three access points so brand new hardware in place just before the holidays. Was having the same issue with the old hardware.[/b]

I have included the logs from the past couple of days from the three switches. If anyone has any ideas on what is happening and what we can try to improve the situation would be greatly appreciated.

I would bet on ESD.
