How to configure priority

Hi,

I’m using Mikrotik 3.28 OS, during peak hours my backhaul bandwidth will be full. I want to set priority to few customers so that even though my bandwidth is full these customers should get the configured bandwidth rest of the customers need not get the configured bandwidth. In queues i have given priority as 1 but it doesn’t seem to be working. What is the configuration to be done please suggest.

Thanks,
P.Srinivas
