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.
