3850 using autoqos setup for etherchannel

[gp1200x]

On the 3850 ....a trunked stack to a main core stack....what are the interface commands for trusting packet markings

The portchannel has two connections to the core..  read in the manual not to apply it to the portchannel interface itself yet it took the trust cos command on it but no policy map commands.

If I check the policy map on the GI interfaces themselves they seem to placing packets in the correct ques....is this config okay?

interface Port-channel1
 switchport trunk allowed vlan 209,509
 switchport mode trunk
 trust cos
 storm-control broadcast level 0.50
 storm-control multicast level 0.50
 storm-control action trap

interface GigabitEthernet1/0/48
 switchport trunk allowed vlan 209,509
 switchport mode trunk
 trust cos
 storm-control broadcast level 0.50
 storm-control multicast level 0.50
 storm-control action trap
 channel-group 1 mode active
 service-policy input AutoQos-4.0-CiscoPhone-Input-Policy
 service-policy output AutoQos-4.0-Output-Policy

interface GigabitEthernet6/0/48
 switchport trunk allowed vlan 209,509
 switchport mode trunk
 trust cos
 storm-control broadcast level 0.50
 storm-control multicast level 0.50
 storm-control action trap
 channel-group 1 mode active
 service-policy input AutoQos-4.0-CiscoPhone-Input-Policy
 service-policy output AutoQos-4.0-Output-Policy

Hi Yes your good , ios-xe trust packets by default too so once source is marking it right it will carry it so you don't need it on the port-channel itself and you have enabled the physical members so your good , I would remove the trust cos doubt you need it with the auto qos in place really

another check to show its working , ignore the 0 after it i was informed by TAC that's for future development
