I am implementing QoS on C3850 and trying to find a good document that would describe commands that I would need to verify if my implementation is successful.
1.
Is there any way how I could see per port class statistics ?
Something like this
show policy-map int g1/0/15
shows aggregates - classification counter aggregates all packets belonging to the same class of the same policy which attach to different interfaces.
2.
Is there any command that I could use to see what queues my classes use, like in the one below I can see I am using three queues, but have no clue how I could see what classes use them. Reading some documents I guess two of them might be priority queues.
show platform qos que stats g 1/0/15
DATA Port:11 Enqueue Counters
-------------------------------
Queue Buffers Enqueue-TH0 Enqueue-TH1 Enqueue-TH2
----- ------- ----------- ----------- -----------
0 0 0 0 64440167
1 0 0 0 13709990
2 0 0 0 1912882424
3 0 0 0 0
4 0 0 0 0
5 0 0 0 0
6 0 0 0 0
7 0 0 0 0
3.
show platform qos dscp-cos count g 1/0/15
Ingress DSCP0 787315 0
Ingress DSCP1 0 0
Ingress DSCP2 0 0
Ingress DSCP3 0 0
Ingress DSCP4 1 0
What does the first column show - I guess the number of packets/frames that correspond to Ingress/Egress DSCP/COS ? What is the second column about ? I have zeroes everywhere.
Thank you.
Vlad
