This read-write object sets the maximum permissible queue depth, the max-threshold, beyond which a packet presented to the queue will be dropped outright, whether in tail-drop mode (dropped once the queue is instantaneously full) or random-drop mode (dropped once the average queue depth exceeds this threshold), and like the min-threshold it lives in the action table so differently classified traffic sharing one queue can have distinct limits. An admin tunes this to define the hard ceiling on queue occupancy for a given traffic class's action. For example, an admin wanting a best-effort traffic class to be dropped more aggressively than premium traffic sharing the same physical queue would configure a lower max-threshold for the best-effort class's action entry.
