dscp configured at uplink port at C9300

[interfacedy]

Hello We have a switch where one port g1 is connected to end device and two other ports g2 and g3 are channeled to uplink device. The command auto qos trust dscp are added at g0 and also at both g1 and g2 instead of channel port as it is not supported at C9300. Is this correct way to configure? Thank you

Hello
yes apply the qos to the physical interfaces then add those interfaces into the port-channel.

@paul driver  Thank you very much for your reply! If the end device is AP, which is connected to g1, and both g2 and g3 are layer 2 trunk port, do we still use command "auto qos trust dscp"?

Hello
I would trust auto-qos cos on the g1 but not on the g2-3 as im quite sure auto-qos isnt supported however you could manually trust qos cos on them.

"I would trust auto-qos cos on the g1 " as you mentioned above. why it is trust auto qos cos instead of dscp? thanks
