QOS for DSCP Markings

I have had QOS on some older routers and switches with the following commands

class-map match-all VOIP-SIGNALING

match dscp af41

class-map match-all VOIP-RTP

match dscp ef

policy-map VOIP

class VOIP-RTP

priority percent 15

class VOIP-SIGNALING

bandwith percent 3

These commands don't work on the new code, can you give me the commands that replaced this or can do this on the new code.

QOS for DSCP Markings

The cisco is a 3850 with version 3.2.2 se.

match dscp af41 command works.  I can't give the call a name so the first statement

class-map match-all VOIP-SIGNALING does't work

Then on the policy map when I try to use that class

Policy-map VOIP

Class VOIP-RTP               * because I can give the class map on name this statement does't work

priority percent 15             * this statement doesn't work

class VOIP-SIGNALING     * again this statement does work because of not being able to name it

bandwidth percent 5          * this statement doesn't work

I just tried it again and this is what I got in:

class-map match-any VOIP-SIGNALING

match dscp af41

class-map match-any VOIP-RTP

match dscp ef

policy-map VOIP

class VOIP-RTP

priority percent 15

          Error on this one that I can only use priority with level is supported on this platform?

class VOIP-SIGNALING

bandwith percent 3

So I am assuming the any on the match will be fine, however what about the level error on the priority command?

Oh, a 3850 L3 switch.  Likely its QoS MQC is much restrictive compared to a router.  I'm not familiar with that platform, but is IOS configuration guide probably has a section on QoS.  Have you reviewed that?
