I have quite small network - over 10 RB’s (133,153,x86.. etc. etc.) and many redundant paths to the one point. The problem is that RSTP doesn’t discover ports as alternate port to the root bridge, so I guess it cause some kind of loop - in some RBs all interfaces transmit data TX ( few mbits) but doesn’t recieve anything. (RX = 0 kbps). Where is the problem ?
