Any QoS queue that is dropping packets is identified. The relative priority of the queue determines the severity level of the issue that is generated in the Issue List. The table below shows the severity generated for each queue's Per-Hop Behavior (PHB) and DSCP value that are commonly associated with applications. Drops in high priority queues will generate Error issues, while medium priority queues generate Warning issues. The lowest priority queues, including the scavenger queue, generate Info issues.
