Hi,
I noticed your post and I checked on some MikroTik routers with ePMP 2000 attached and you're right: I can see very big numbers on Rx Pause with an increment of more than ~20000/sec.
People from Cambium, why there is this issue?
Tx flow control and Rx flow control are disabled on interfaces...
I can see lots of Rx Pause also on Force 200 ports.
0 Rx Pause on all other devices (Ubiquiti, MikroTik, Mimosa...)
