Alright, so looks like the WAP371 is placing what should be tagged traffic onto the native VLAN. Was wondering why I was getting connection drops, so I checked my syslog and found IP Spoofing detections on my SonicWALL as well. This is causing all sorts of connection issues, as you might expect. It seems to be after a certain amount of traffic; It's pretty consistent in that respect.
Equipment:
- SonicWALL NSA2600
- 4x HP A5120 Switches - IRF'ed and MLAG'ed to SonicWALL (Latest Firmware)
- 4 WAP371's - 1.2.0.2 Firmware
To ensure it wasn't the other gear and/or configuration, I cut it down to a single switch with no LAG to the SonicWALL, still the same thing. Also tried disabling jumbo frames, etc... No dice.
See below screenshot... This is happening all the time. Absolutely unacceptable. I tried disabling the untagged (native) VLAN completely via the WebUI and that didn't help either.
