QoS on trunk interfaces

Greetings,

 

I just want to make sure that the access switch trusts all QoS markings and gives voice priority by default if there was a congestion.

 

Therefore, I am planning to set "mls qos" global command and "mls qos trust dscp" and "priority-queue out" on all the ports including the port channels. 

 

Do I have to set those last two commands on the individual physical ports that comprise the EtherChannel or just on the EtherChannel.

 

Please let me know, that part is it not clear for me.

 

Regards,

Edouard.

yes you need to enable all the port of access ports where the devices connected.
