Steffen,
Just to clarify what Krishna was saying. Here is the command reference mls qos queue-set output qset-id threshold queue-id drop-threshold1 drop-threshold2 reserved-threshold maximum-threshold There is no threshold 3 configuration because it is 100% and not configurable. Where you have 75% is the reserved-threshold not threshold 3. Moving cos and dscp values to threshold 1 and changing threshold 1 while keeping threshold 2, reserved-threshold, and maximum-threshold at 100 is just the easiest way to do it in the lab. If you use auto qos on an unused port like I do it will change the default mappings so everything is not in threshold 1 allowing you to move just values you want into threshold 1.

But as I said when COS 5 is the only COS in Queue 1, which Traffic/COS could fill T1 and T2 up to 100% when COS 5 is only mapped to T3? Regards Steffen 2012/10/21 Krishna <vinayak_...@yahoo.com> steffen, your approach is not right way of doing it because when u look the threshold values of the queues you have allocated max threshold is 100 and reserved threshold is 100, guess what both threshold i.e. t1 and t2 takes up to 100% value when desired and that being said after t1 and t2 were filled it comes to t3 which has 75% i.e. it is the last threshold where it will take/borrow the memory value from reserved threshold when desired. long story short... right way of doing it either assign it to t2 or t1 and assign threshold value of 75% for correct approach... thank you krishna. _____ From: Steffen Bruening <stbruen...@gmail.com> To: Pixar Perfect <pixarperf...@live.com> Cc: ccie_voice@onlinestudylist.com Sent: Saturday, October 20, 2012 6:38 PM Subject: Re: [OSL | CCIE_Voice] LAN Qos questions I have this seen this also, to be honest I think it shouldn't matter whether it is in threshold 1 or 3 as long as no other COS is in same Threshold of queue 1 of queset 2. When you leave in in threshold 3 I think you should be fine with: mls qos queue-set output 2 threshold 1 100 100 75 100. Maybe I am completly wrong but thats they way I understood this. Regards Steffen 2012/10/20 Pixar Perfect <pixarperf...@live.com> The requirement is as follows on Lab 2 QOS section of the 5-Lab Handbook. "For traffic being sent to the Site A gateway ensure that the traffic marked with COS 5 is dropped if the queue 1 is 75% full" The Solution guide (page 408) has the following solution. mls qos queue-set output 2 threshold 1 75 100 100 100 --> queset is preconfigured on the port to 2 mls qos srr-queue output cos-map queue 1 threshold 3 5 .. My interpretation was to move the Cos 5 into Q1t1 but the command says threshold 3 .. is this just a typo or am I missing something obvious.
