QOS Command differences

[toddvictor18]

I am currently needing to upgrade 3750x running  15.2.2 stacks to cat 9300s running 16.6.5

Our 3750s use mls qos. But this command is unavailable on the 9300s. Some of our interfaces on the 3750 have the configs below. I've setup auto qos on the 9300s but am unsure on how these commands below would be applied with auto qos.

srr-queue bandwidth share 10 30 40 30
srr-queue bandwidth shape 3 0 0 0
priority-queue out

The new catalyst 9k platforms use a different QOS model to the 3750, MQC as opposed to MLS, if you check out this guide it will show the config needed and highlight the differences
