I got my ERPOE-5 last week.
When I use iperf3, I find the retransmit value is a little high. Although there are no problem in normal use.
I test both default firmware (1.2.0) and the lastest firmware (1.9.0). This doesn't happen in firmware 1.2.0.
I'm just wondering it's usual or not.
Firmware 1.2.0
