When I run the two below commands I get:

 

Switch#show policy-map interface GigabitEthernet1/0/48
 GigabitEthernet1/0/48

  Service-policy input: AutoQos-4.0-Trust-Dscp-Input-Policy

    Class-map: class-default (match-any)
      444294 packets
      Match: any
      QoS Set
         dscp dscp table AutoQos-4.0-Trust-Dscp-Table

  Service-policy output: AutoQos-4.0-Output-Policy

    queue stats for all priority classes:
      Queueing
      priority level 1

      (total drops) 0
      (bytes output) 1469363

Switch ports are configured as such:

interface GigabitEthernet1/0/48
 description Uplink to ISP's Switch
 switchport mode access
 bandwidth 5000
 speed 100
 duplex full
 auto qos trust dscp
 spanning-tree portfast
 service-policy input AutoQos-4.0-Trust-Dscp-Input-Policy
 service-policy output AutoQos-4.0-Output-Policy

 

Shouldn't I see some bytes for the  Class-map: AutoQos-4.0-Output-Priority-Queue (match-any)? I want to ensure my voice traffic which is marked as 46 is properly being prioritized. Thoughts from the output provided?

 

Thank you in advanced for any input!

I just found this thread: https://supportforums.cisco.com/t5/lan-switching-and-routing/auto-qos-3650/td-p/2768655

Is the show policy-map interface not support on the 3850 like with the 3650?

I have the same question with the packet counters remaining on 0, for 9200L switches running 17.3.3.

 

Isn't that supported like it is on the 3750/3560/.... ?
