Hi,

Unfortunately, QoS configuration is different per platform and per IOS. So, you would have to look at the 9400 and look up the commands you need. Here is a link to the config guide.

@bilalsheikh77 : See the config on Cisco 9400 for Qos trust dscp. Check the link below and search for auto qos config. No issues with the configuration.

Device(config)# interface gigabitethernet1/0/18
Device(config-if)# auto qos trust dscp
Device(config-if)# end

Make sure this command is manually entered into the configuration.  

By default, this command is not present.

Hey Leo, 

what is better at this point just using the auto qos dscp or having it in a policy map and then calling the policy map in the interface level. i like the policy map option for better control. 

Any thoughts ?

Have a look at the default configuration of the Cat9k switches (all of them). 

They all have a "default"-like QoS config.  

QoS config for the Cat9k is very different to any previous "classic" IOS config.  Behaviour is totally different but make sure to add the following line in:

qos queue-softmax-multiplier 1200
