Upgraded a switch to 1.3.7 tonight/this morning and noticed that flow control is not showing as "on" on any of my Gigabit interfaces (e.g. backhauls).

What is used to determine if Flow Control shows up as "on"? it's definitely enabled on the ports tab, but the status tab doesn't show the two little arrows.

This is a "known" issue with UBNT 1G devices, they are fixing this. "They" have it turned OFF on a lot of their newer devices.

So then why would I have seen pause frames prior to upgrading the switch firmware?

I am just telling you some of UBNT 1G devices do not have Flow Control enabled.

For example the AF5X had flow control disabled and is just now enabled with newest RC version.

Also most of their 1G airMAX radios have FC disabled.

What radio is this?

airFiber24

What version firmware are you running on AF24 because if it is v3.X then that was discussed on the UBNT forum in the thread above and you were in that thread? Downgrade AF24 to v2X and it works

I feel stupid. I started rooting around in the configuration and someone forgot to click "FC On" in the airFiber *sigh*.

We all do stupid things, it happens but also note that v3X on AF24 FC is disabled [BUG in UBNT firmware], stick with v2X

Thanks! I did know about that.
