It also appears as if the port details were affected too. Pause frames seem to be reported by the switch at about 3X what the router interfaces show and on some APs I'm showing Billions of RX pause frames (the switch was rebooted 10 days ago).
While this was occuring that switch status page did show sustained CPU usage quite high (upper 90%s) and then I noticed that the switch showed as disconnected in the netonix manager. I edited the switch in manager (not making changes but to force reconnect) and a few seconds later the switch showed back online. I switched back to the tab with the switch UI and suddenly traffic had returned to normal. Rechecked CPU usage and it was hovering 60-70%.
I thought we had some SNMP monitors on some of the ports, but upon review we didn't as I was curious to know if the incorrect data was also reported to SNMP. In review of the switch log the only note worthy entries were that 6 hours prior we had warning about excessive pause frames from an AP and just about the time the problem resolved the same occurred on another port. Historically these notices are rarely seen on this switch, which makes me wondering if incorrect status were driving the messages.
All of this was very strange and with unreliable numbers it's a tough one. The log is below and I've attached several screen pics as well.
Presently running 1.5.0 and I'm thinking of upgrading to 1.5.1RC
