Creating a thread pointing towards a wikipedia article is not particularly helpful on the forums. If you're looking to provide advice, do it, explain it, and don't rely on a singular link.

It's pretty easy to configure the switches to protect against it. The link tells you how.

Also my Cisco Meraki is pretty anal about isolating VLAN traffic.

True but that's not the point. The point is to express outwardly help and knowledge and even opinions on why you feel that is helpful or relevant.

I agree its useful but I agree with RCoon you should post something content wise...when I first saw your OP I almost reported it as spam until I verified the link.

Why not add some useful knowledge and use that link to back it up? VLanning is critical to understand and hopping is an ever present danger due to how many folks aren't aware or mismanage their networks.

I would much rather have a conversation with you about it and absorb your experienced based knowledge than see a link with no dialogue. Just sayin.
