Re: Switch QOS question

COS 5 already in egress priority queue 1 (which you've explicitly enabled)

5

--
1-1
can see you have marked dscp 46 and overidden 40 here
mls qos map cos-dscp 0 8 16 24 32 46 48 56
good
"Queue 2 - Cos 4 , 6, 7"
already done with
mls qos srr-queue output cos-map queue 2 threshold 1 4
mls qos srr-queue output cos-map queue 2 threshold 2 6 7
just different thresholds assigned - ok no problem
for
"Queue 3 - Cos 2 , 3"
already by default
 2   3
-------
3-1 3-1
for
"Queue 4 - Cos 0, 1"
already by default
0    1
------
4-1 4-1
"Guarantee queue 1,  25% of the bandwidth.
 The other queues should share the bandwidth as 30 40 30."
you've applied at the interface level here
"srr-queue bandwidth share 25 30 40 30"
and finally
"When Queue 2 reached 40% capacity COS 4 packets should be dropped"
unless the following is a requirement:
mls qos queue-set output 1 threshold 2 40 100 100 100
I would change to:
mls qos queue-set output 2 threshold 1 40 100 100 100
as COS 4 maps to queue 2 threshold 1
i'd also trust COS on any ingress trunk ports for uplinks that you may or
may not have!
I'm guessing you've skipped the L2 QoS section
:)
