Hello, all.
When configuring QoS on 3750s/3560s, we're mapping packets to particular interface output queues with commands such as:
mls qos srr-queue output dscp-map queue 1 threshold 2 32
The queue numbers available for use in this command are 1-4, i.e.,
mls qos srr-queue output dscp-map queue 1 threshold <etc.>
mls qos srr-queue output dscp-map queue 2 threshold <etc.>
mls qos srr-queue output dscp-map queue 3 threshold <etc.>
mls qos srr-queue output dscp-map queue 4 threshold <etc.>
The command to see what's actually being enqueued, dropped, etc. is:
show mls qos interface < > statistics
The end of the output of this command shows:
output queues enqueued:
queue: threshold1 threshold2 threshold3
-----------------------------------------------
queue 0: 11 0 0
queue 1: 7322430 17421520 22046162
queue 2: 0 0 81775734
queue 3: 23048 0 7294764
output queues dropped:
queue: threshold1 threshold2 threshold3
-----------------------------------------------
queue 0: 0 0 0
queue 1: 935 45106 0
queue 2: 0 0 185537
queue 3: 2 0 0
Note that these queues are numbered 0 - 3, and not 1 - 4. We've been assuming that the first queue number in the "mls qos" (i.e., 1) command maps to the first queue (i.e., 0) in the "show mls qos" command.
We're wondering if anyone can confirm this from certain knowledge, or if perhaps we're missing something.
Thanks much for any help you can give!
