Oh indeed it does. Shame on me I didn't see that in the menu. nonforwardingreason shows a disputed BPDU condition. Now why should that suddenly appear after the reboot of the switch? Well, is there a command to see where exactly that BPDU is coming from? Behind that port *should* be a private network with another switch but no more bridging back to the main network... If there is no built-in function I guess I'll check with a network sniffer.
