Usage Guidelines

After running the qos tail-drop-profile command in the system view to create a tail drop profile, you can run the qos queue max-length or qos queue max-buffer command in the tail drop profile view to configure a queue. You can apply a global tail drop profile to a physical interface to drop packets at the end of a queue.
