Note sure whether adding below will help
priority-queue queue-limit 2
The queue limit of the priority queue should be the configured
automatically to use whatever remaining, but in your case it is still
taking 15..
queue-limit ratios: 5[queue 1] 84[queue 2] 5[queue 3]
1[queue 4]
1[queue 5] 1[queue 6] 1[queue 7] 15[Pri Queue]
suspecting whether that is the reason why your queue 4-7 limit is
detected as "0" even though u configured "1".. just a thought.. hth

Subject: Question about 10 Gig ports w/ 6509 & Sup 720 - QoS
All-
Configuring a new 10 Gig blade (6509 - Sup720) for QoS, and having some
issues. I think my understanding of the queuing/bandwidth on the new
blades
might be a mis-interpretation issue. So, any help would be appreciated
First thing I should mention is the design methodology. The only thing
we are
doing is queueing voice, video, and all else. The new 10 Gig blades are
1P7Q4T. Therefore, I need to weight the queues appropriately, and the
majority of the traffic will be going into Queue 1 threshold 1 (default
COS
0). There is no requirement for scalability into the other queues;
therefore,
the lowest weight would be good.
Voice is COS 5 (mapped to queue 8)
Video is COS 4 (mapped to Queue 2 threshold 2)
Class-default mapped to (Queue 1 threshold 1)
I am getting the following errors on bootup:
Warning: TenGigabitEthernet2/1 Queue 4 Bandwidth is set to 2 but
queue-limit
is 0. Please change queue-limit setting!
Warning: TenGigabitEthernet2/1 Queue 5 Bandwidth is set to 1 but
queue-limit
is 0. Please change queue-limit setting!
Warning: TenGigabitEthernet2/1 Queue 6 Bandwidth is set to 1 but
queue-limit
is 0. Please change queue-limit setting!
Warning: TenGigabitEthernet2/1 Queue 7 Bandwidth is set to 1 but
queue-limit
is 0. Please change queue-limit setting!
(all interfaces giving this error).
Am I mapping/queuing incorrectly? Any Advice????? I am in a pinch
here.
