This counter tracks the total number of packets forwarded by the class-5 egress expanded traffic shaper on a port, measuring the volume of traffic successfully handled by this quality-of-service queue. Class 5 typically represents a specific priority or service level in a multi-level QoS hierarchy, and monitoring this counter helps verify that traffic shaping policies are working as configured. Operations teams check this to ensure that class-5 traffic (e.g., video or low-latency applications) is being processed without bottlenecks.
