Switch errors out on hard boot

[petercoetzee]

Hi Guys, Ive never seen this before, hoping its a flow control or negotiation issue. We have rolling blackouts at the moment, backup power eventually fails. When power is restored, this particular switch stops passing traffic to sectors attached to it. Its still reachable remotely and all else seems good. Ive since added a watchdog to each port as a band-aid.

If you haven't already definitely try disabling flow control.
Can you post the logs for the switch if this occurred during it's present uptime?

Based on the stats shown, it looks like the problem is not so much that the switch is failing to pass traffic TO the sectors, but rather receive traffic FROM them. You said the power is failing & I noticed PoE is disabled... Are you sure the sectors are powering up properly after the power failure? Also, is it normal for your switches to show so may errors?
