got a weird message in logs. (1.4.7rc7)

we were doing some tower changes, so i cleared the logs after. I saw a bunch of flowcontrol stuff, but figured it may be going haywire when we were swapping and downing links.

Anyway: Interesting:

We have AF24 in Port 2: Flow Control is OFF
Nothing in port 3
Port 8 + 10 are new Rocket AC PRISMs (running v8 current)

*we have Flow Control off on the port (its on on the AF, not sure if that matters) as we would only get about 350down/600up through the AF, and with it off we get abour 575down/600up

**no idea why we are not getting 740/740 if this is really full duplex. We have it aligned perfectly, with -55 all around, on a 2000' shot, with TX powers reduced on the AFs.

I figured this was interesting to look at. wondering if we really do have some issue with pause frames?

This is a known issue with airFIBER firmware, UBNJT has acknowledged they have a FLow Control Pause Frame bug.

It has also been reported to affect airMAX AC radios.

Do a search for FLow Control on our forum and UBNT Forum and read up on it.

Here is 1 post regarding Pause Frame Storm with AF radios: viewtopic.php?f=17&t=2375&p=17404&hilit=pause+frame#p17397

I have read up on it a bit.

Should i keep flow control enabled in the AF? And in the Netonix?

Or disable One, or the other?

I had better performance when we had netonix FC off. But i didnt remember to test it with the AF FC turned to off.
