I'm trying to understand the priority-queue out command configured on an interface.
Based on what I have read, here is what it does : the Priority Queue (Queue 1) on the switch will be emptied before any other queues (Q2, Q3, Q4).
But how can you tell which traffic should be sent to Q1 ? Is this done using a class-map and a policy-map ? Based on this document : https://www.cisco.com/c/en/us/td/docs/routers/connectedgrid/cgr1000/1_0/software/configuration/guide/qos/cgr1000_Book/qos_priority_cgr1000.pdf ... you would have to configure "priority level 1" in your policy-map. Is this correct ?
We have a switch here configured with priority-queue out, but I can't find any class-map or policy-map on it. Is it possible to assign traffic to the priority queue in another way ?
