I am trying to enable auto-qos on a 3750V2 stack of 3 switches and it doesn't appear to run correctly. They are all IP base running 15.0.2 code.
If I run auto qos voip cisco-phone on the range of interfaces it installs the correct commands on the interfaces but it does not produce the mls commands that I normally see on my other switches. Enabling mls qos before or after the above command does not make a difference. If I delete all the commands, reboot and start over I get the same results. I can copy the commands from another switch but it bothers me that it does not appear to run correctly on this stack. I do not get any errors when I type the commands and they take a while to run as if they are working properly....but no mls commands show up except for one which is mls qos map policed-dscp 0 10 18 24 46 to 8.
What am I doing wrong or forgetting?

The AutoQoS command that "don't show" with your 15 IOS might be because they are already the defaults. I haven't used 15 IOS on 3750, nor do I use AutoQoS, so I don't know this is the case, but I do know AutoQos and QoS default do vary per IOS version.

I was using code ipbasek9-mz.150-2.SE2 on 3750V2 POE ip base switches. I upgraded two stacks to 150-2.SE5 to test and I now seem to be getting the mls commands generated consistently - wiped and retired a half dozen times with no issues. I don't know what the issue is but it seems my SE2 code is flawed..the SE5 is giving me the commands I thought I should see. This bothers me since I upgraded about 50 stacks to the SE2 code and never saw this issue until I started configuring new V2 stacks to add. Stacks are X/E and some standalone V2 stacks - haven't added a new X stack to see if I have the same issues. I guess time will tell and at least I have a workaround..
