Hello,
We recently installed a new stack of 5420Fs running firmware version 31.5.1.6 and I keep seeing these log messages multiple times a day "<Erro:STP.InBPDU.Drop> Slot-1: Port=1:45: Illegal STP BPDU format 45." I can't really seem to find any documentation online regarding this Illegal STP BPDU format error message, which is why I am here. When I check LLDP neighbors on that port, it looks like there is just a laptop on the other end, I am getting a Microsoft MAC address on the port. Should I configure this port as an edge port? Looks like it is set to auto, but is showing up as a point-to-point port which doesn't seem correct, but maybe it is? Not too familiar with STP on EXOS.
Thanks!
