[Sorry, I missed this sentence in my first reading]

We'd also hope that the IDS would alert on the intrusion due to the 
attempted co-opting of the switch, since it's a part of our 
infrastructure we would want it monitored, and if that were successful, we 
would also hope that it would also alarm on the loss of multi-MAC traffic on 
the link.  'Alarm on what we know is bad' isn't as encompassing as 'Alarm 
because we haven't seen anything good', and I'd expect to be able to have 
a mix of the two.
