WS-12-250-DC - LVD - Will not power back on Automatically

Correct, all 4 of those boxes are unchecked currently. We had to disable the "Discovery Tab". The Ubiquiti(UBNT) was never checked.

Please explain "We had to disable the "Discovery Tab"
Why did you have to, what reason?

[Nick-ZetaBroadband]

I cannot find the post now, I tried to locate it again but was unable. You were helping someone else with RSTP and mentioned disabling the Discovery Tab.

This is what I meant meant earlier by disabling RSTP, that is my fault for explaining VERY poorly.

Once we disabled the Discovery Tab traffic started to flow across the 2 ports and it stopped its Discarding State.

OK so lets clear things up.

You had to Disabled the "Discovery Tab" or "UBNT Discovery Protocol" to get RSTP to work properly?

[Nick-ZetaBroadband]

The Discovery Tab.

So would you mind:

1) Enable the Discovery Tab again and verify it breaks RSTP. For some reason this only affects some networks as it is not broken for my WISP an have everything enabled to test. - WEIRD

2) If you verify it breaks RSTP for your network would you allows Eric access to your switch?
He would have to Enable the Discovery Tab then see what is happening so doing so does not lose control of your switch correct?

All Discovery has been turned off (including the tab).. Ports 3/4 were still in a disabled state. I had to completely disable RSTP to get the devices on those ports back online and traffic flowing after fixing the LVD issue.
I'm not sure why it was disabling forwarding on those ports -- the devices connected to those ports are simple management for the AP.. Everything connecting to the AP is VLAN'd back to our PPPoE NAS.

The reason I had not upgraded was due to RC/Beta status..

Sorry for the confusion -- my tech was relaying messages for me while I was on site.

Maybe your issue is not a bug then?

The only "possible" bug that we are aware of with RSTP was due to the UBNT Discovery routine which Eric thinks he fixed it. Other than that we have tested RSTP extensively.

If the RSTP bug with UBNT Discovery is not fixed then the switch CPU utilization will go to 100% +/- if you enable UBNT Discovery.

So try leaving RSTP OFF and enable ALL the option under Discovery and see of your CPU goes to 100% +/- which is the only reason why RSTP had an issue but as I said earlier we think we fixed it as the person we were working with (one of the few that jad an issue) has not gotten back to us if the last patch fixed it which usually indicates it might be fixed as when people do not have an issue you hardly hear from them.

However not all people experienced the issue which is weird.

I'll have to try that another time -- I'm 1.5hrs away from the site now and don't really want to break something and have to drive :)

[Nick-ZetaBroadband]

Either way I'll let you know -- I've got about 6 of these deployed and two more going out today...
