Assessing hardware and assigning classes to queues

Most Cisco hardware used in modern-day networks support at least four output queues for scheduling. If there is legacy hardware that doesn't support four queues, we might need to club two traffic classes into a single queue and use different WRED thresholds. This would ensure that the two traffic classes that are clubbed together still have some differentiation between them.

The hardware queues are generally mentioned as 1p3q, which means that the port has one priority queue and three other queues for output scheduling. If a port queue structure is 1p2t, we would club the silver and best effort traffic classes into one queue, and if the queue structure for a port is 1p5t, we would just use ...
