Split Brain Switch

Apologies if this isn't the right group for this question.

Can anyone explain what a split brain switch is? I've tried to locate information on this without much luck.

Thanks, Beery

The phrase split brain I'm only familiar with in the context of DNS architecture e.g. split brain DNS.

It's conceivable that someone might contort the nomenclature and refer to a switch that supports VLANs as being configurable in some sort of split brain setup, but best I can tell that's far from any sort of standard terminology for switches.

A google on "layer 2 split brain" talks of split brain as a rather undesirable situation that can occur if you goof up a high-availability pair of their firewalls:

I am, hwoever, curious what you come up with and what motivates the question.

like Todd wrote, this is the case if all machines in a ha setup think they must be master. Some switches supports ha cluster setups, probably there you got the term from.

cheers
