I made a little booboo today with Spanning Tree. I have a new VDX fabric in logical chassis mode and tried to connect 2 ports from a Cisco 3020 in an HP blade chassis. I knocked the whole fabric offline from the core since the ports were flapping mac addresses back and forth. My question is, will using LACP to aggregate the 2 ports fix that and is there a way to prevent that from happening again in case someone else makes the same mistake? Is this waht Edge Loop Detection is for?
