Hey Brian,
I see... FTP traffic can basically get more than 90% of traffic with my first configuration during congestion while other traffic would be guaranteed the other 10% of traffic during periods of congestion.
My real uncertainty lies in the "class-default". Does system-generated traffic (routing processes, etc) fall into this class or would that traffic potentially starve if all remaining bandwidth (to fill up 100%) was guaranteed in the class-default (of course this could only be done by changing the "max-reserve-bandwidth" value to 100%).
TIA,
Ken

Ken,
Yes there is a difference. In the first configuration non FTP
traffic is not guaranteed bandwidth in the case of congestion. In the
second configuration, non FTP traffic is guaranteed 10% of the output
queue in the case of congestion.
