Lets take it to the extreme: someone (accidentally or intentionally)
resets (or otherwise changes) the switch configuration. With separate
switches, each segment can talk freely to all other servers on the
segment but not outside, since the FW watches that route. For one big
switch connected to an outside FW, all segments can talk to all
segments (if the switch behaves as a L2 one). What about 6500 with
FWSM? does resetting the config prevents it from seeing any traffic?

On C6500 platform all ports are in `disable' or `administratively down'
state after clearing switch configuration depending on type of images
(CatOS or Native IOS) currently running on the switch. So there's no
danger in this case.
