Thank you for your response. You confirmed what I understood to be how it works, but for some reason it isn't working like that, and I can't understand why. The alias gets assigned through heartbeat, during a failover, but traffic routes through that alias as if there was no shaping going on at all. In other words it just isn't working the way that it should be working. I am not even sure where to look for problems or errors. I don't see how my configuration can be wrong because it is shaping traffic just fine on the physical adapter . .. If anyone can think of other suggestions, I would greatly appreciate it.
