STP problem

I have Catalyst 2950 with IOS version 12.1.12c. When some ports are in blocked state, on my show spanning tree command i get , instead of blk, bkn*.

Does anyone knows what is it?

Re: STP problem

Broken state (BKN*) for an inconsistency status. The port would be either root inconsistent, loop guard inconsistent, PVID inconsistent, or type inconsistent.
