I just filtered spanning-tree out of a small sample file that normally causes the Warnings.... and no more Warnings.
I'm happy I get a nice clean run now but still would like to know why we can't replay STP using tcpreplay. I was just thinking that there might be a valid use case by injecting stp and seeing how the switches react. Anyways, thanks for pointing out the packet to me, it helped locate the issue. How did you locate the first packet that gave the error #887 ?
