Solved! This problem was resolved when we disabled in-band management on the AirFiber and added a secondary eth cable for management purposes. Legacy Trango PtMP products have weird TCP stacks, in particular their 900MHz equipment, something goofy was happening with that combo. I read that the AFs do some weirdness with multicast traffic when in-band management is enabled.

The AF should essentially be acting as a transparent bridge.

Before: Me – (Procurve 1810) – (3X Dragonwave HC in LACP) - (3X Dragonwave in LACP) – (Procurve 2848) – (APs & BHs) After: Me – (Procurve 1920-24G) – (Ubiquiti AirFiber 24 HD) - (Ubiquiti AirFiber 24 HD) – (Procurve 1920-48G) – (APs & BHs) Everything works as expected with the exception of subscribers behind three different Trango M900APs. The M900APs are manageable, but the connected clients are not. The M900AP can always ping the clients but the Procurve 1920-48G switch and other devices further back cannot either. The M900AP clients also are not able to establish PPPoE sessions. Its gets weird- If we reboot the M900AP all the clients become manageable and establish PPPoE connections but this only lasts unpredictably anywhere from 10 minutes to 3-ish hours. Weirder- Only this tower that received the Procurve 1920-48G has problems with the M900APs. Other towers that are backhauled off this switch and also received new Procurve 1920-24Gs switches and have M900APs do NOT have this same problem. I’m running out of ideas to try :/ Nothing else changed in the network. Basically it’s something with the AF or the Procurves, I think? Incidentally, we put these 3 APs on the old Procurve 2848 and routed them back over the Dragonwave and it worked just fine for a few days. Ideas? `S
