I dont believe the utilization would have to be pegged for the
priority to be "active" for your FTP traffic. Priority queue basically
forwards all packets other than FTP out its interface first before any FTP
traffic is serviced.
If you're intimately familiar with the network traffic on that fast
ethernet, you can try using custom queueing.
But basic WFQ should be sufficient to prioritize low traffic,
interactive applications by default.

Subject: Priority queue
Dear all,
I have a Catalyst 6509 running with Fw 5.4(2) & NmpSW 5.5(11). And the
MSFC is running on 12.1(3a)E4.
One strange point that cannot be explained is the priority queue applied on
a VLAN which is connection to a WAN 100Mbps fastethernet.
The priority queue is to put the FTP traffic low priority. After applying
the priority queue, the time for a daily FTP job has been extended from 3
hours to 5 hours while the traffic loading of the link is only around 10%.
The duration come back to 3 hours after removing the priority queue.
Can someone help to give advice?
Thanks
Felix
