@hacks4pancakes @risottobias @Xavier lol, I was once accused of taking down the network for a major theater wide military exercise with an ARP storm. Turns out, someone took an unmanaged consumer hub and plugged it into the exercise network. And then someone took an Ethernet cable, plugged one end into the hub, and the other end into the same hub. It took the better part of an hour to finally track it down.

@hacks4pancakes @risottobias @Xavier A lesson learned early on at University and at various jobs: Someone will definitely bring a wifi router configured to be a dhcp server in from home and plug it into the network to get better wifi reception on their laptop.

@hacks4pancakes @risottobias @Xavier this is why I always backup and then clear a switch especially all vtp config before storing it in a closet. I love my vtp too much to not use it. 🙂
