I have a TP Link managed switch that I have enabled STP in, but it's not detecting a loop in the network, and brings the entire lan down. I plug two ends of an Ethernet cable into the switch, which creates a broadcast storm and essentially DoSes the whole network.
I have STP enabled, along with loop protect, root protect, TC protect, and others:
As well as storm control, but nothing seems to stop the broadcast storm once it's created:
I don't understand why that's not stopping the loop from happening? Anyone can just plug a cable into itself and bring down the network if I don't get this STP thing to work
