Hi.

It would be interesting if there was a vulnerability that allowed you to
break the VLAN definitions.. I know many companies that practically run
their entire networks together into several Catalysts via VLANS :) Secure
networks and public ones right next to each other.

I thought that based on the nature of VLANS that they would not be
susceptible to attack from the network layer because they switch traffic
based on the port number, not on any content of the frame or packet? Still,
it would be interesting :)

Anyone out there doing fun things with a cisco catalyst?
I am interested in whether or not some one has found a way to go between
vpns, take over routing of a switch, or other reindeer games.
thanks
