Display the Quality of Service (QoS) egress queues statistics. The show output displays either unicast packet stats for each port, or all stats, based on your hardware platform.
show qos cosq-stats
show qos cosq-stats interface {slot/port[/sub-port][-slot/port[/sub-port]][,...]}
show qos cosq-stats loopback-port <1-2>
None
The show command output varies based on your hardware platform. On all supported platforms except the VSP 8600 Series, the show command output displays Out Packets and Out Bytes per interface, which shows the number of unicast packets sent out on each queue for an egress port. VSP 8600 Series uses VoQ queuing architecture, which enables to read the Accepted Packets and Accepted Bytes on each queue. The Accepted Packets and Accepted Bytes show the number of packets and bytes that enter the VoQ for a particular queue on the egress port. The Drop Packets and Drop Bytes show the number of packets and bytes that are dropped when the VoQ is full.
The show qos cosq-stats command displays the following information:
