Simple Queues, are they sorted in hierachy?

Hi Guys,

If i create 2 simple queues, to give priority to packets to a certain destination, will this mean that all other packets get lower priority (if so what priority??) or do i need to put a catch all at the end to priorise the rest of packets?

There should be highest priority and lowest priority queue, otherwise one queue with highest priority won’t do any priority.
