One customer complaint.  Found the customer was looping traffic  
between two uplinks and helped them fix the problem ;-)

Implementation cost: time/labor to implement automatic management of  
ACLs on the customer ports.

Not all that much cost, since we had already developed infrastructure  
to do the same thing for customer configurations.  Maybe 12 hours of  
my time coding and testing.

Honestly, I expected a lot more problems than we've had.  Especially  
given the fallout I'd seen on the networks trying to do it with  
Cisco.  But the Force10 gear didn't even notice the effect, and it's  
been ~2 years since I've even thought much about it.
