QOS Method to prioritize VLAN network

How to use QOS or another method to prioritize VLAN network traffic as below:

Priority 1: VLAN 2 
Priority 2: VLAN 1 
Priority 3: Other VLANs

 

Is there any supporting document to configure and what we need to tag for prioritizing VLAN traffic.

Mx doesnt use dscp itself, Except  for packets with dscp 46 that will be using the Realtime queue

 

You could tag traffic with a dscp, but it depends on your lan/wan design, configurations, components.

Be aware that you should create these rules in a group policy. They deprecated the "old school way" of doing it. No one is aware of it yet.

Thats weird.  So now we can only use them combined with stateless firewall rules?

Are you sure you really want to do it based upon VLAN?   Any QoS plan should ideally take into account not just the relative importance of the traffic, but also how things like latency, jitter and packet poss affect the application.  It's often the case that the applications that really need QoS wouldn't necessarily  be characterised as the most important.   It's also commonly the case that there's a real mixture of time-sensitive applications and applications with different levels of business criticality running over the same VLAN.
