How do you demonstrate VLAN hopping?. I am trying to show this to a
customer who has mutliple DMZ segments configured as Layer2 VLANs on a

turned on on all ports.

If DTP is turned on then you just need to send the right DTP packets
and turn on trunking. Check out yersinia @ http://www.yersinia.net/
