Hey,
That command is assigning COS value 5 to Queue 1 Threshold 3.
Depending on what DSCP value is mapped to COS 5 in the mld qos map
cos-dscp mapping will determine what traffic is placed in that queue
and threshold. I have seen COS 5 mapped to DSCP 40 by default using
Auto QOS, which

Hi Krishna,
sounds good so far. 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
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
I noticed this and I believe it is a typo further evidenced by the note next to
the command that says something to the effect that that command moves it to q1t1

Hi Krishna,
you will not see Cos 5 in Threshold 1 because this is the default Threshold
for Cos 5. The running-config presents always only the non-default values,
e.g if you put an prefererence command on your dial-peers you will this
only as long as it is not the default value 0.

Isn't it queue 1 takes whatever the value defined in the threshold i.e.

Hi Guys
I am doing a lab and little confused with the proposed solution.
The requirement is that on interface queue 2 queue 3 queue 4 should share
bandwidth as 20 40 40 percentage.
Now what's the best answer.
Interface f1/0/1
Srr-queue bandwidth share 1 2 4 4
Or
Interface f1/0/1
The weights are relative to each other. Assuming priority queue is enabled
on queue 1 and having Srr-queue bandwidth share 1 2 4 4 would mean:
Queue 2 = 2/10 or 20%
Queue 3 = 4/10 or 40%
Queue 4 = 4/10 or 40%
Both ways get the same results. There is no reason for the shape 3 0 0 0

So for your example move 2 and 4 to queue 4 threshold 3. Don't forget to do

Use the auto configured threshold is fine and modify the cos of the

Hi Daniel,
I absolutely agree with you on the first part, regarding that enabling the
priority (expedite) queue will exclude queue 1 from the SRR shaping and
sharing.
However, I don’t think that it is possible to control the bandwidth
percentages using the buffer size allocation “mls qos
Giving it a second thought I have to agree with you. I might have
misinterpreted what Vik said (sorry Vik). So it seems it's impossible to
have both priority-queue out and some form of shaping for this traffic?

You are correct, the srr-queue bandwidth shape means nothing when you
