evils).
I agree. In a perfect world, the default should be to not allow any vlans on a trunk unless explicitly configured. I think Cisco defaults are set so that someone not all that familiar with network gear can plug in a new switch, it will negotiate a trunk, and all vlans will be available on it without a lot of configuration. So like a lot of things, a piece of gear in the hands of someone who doesn't know exactly what they are doing can be dangerous. G
