Display the Quality of Service (QoS) egress queues statistics for the CPU port to display the statistics of the forwarded packets and bytes, and the dropped packets and bytes, for the traffic sent toward the CP. The queue assignment is based on the protocol types, not on the internal COS value. These statistics are useful for debugging purposes.

User EXEC
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 cpu-port command displays the following information:

Indicates the out bytes for the CoS queue. |
|
Accepted Packets Note:
Exception: only supported on VSP 8600 Series. |
Indicates the accepted packets for the Cos queue. |
|
Accepted Bytes Note:
Exception: only supported on VSP 8600 Series. |
Indicates the accepted bytes for the Cos queue. |
|
Drop Packets |
Indicates the drop packets for the CoS queue. |
|
Drop Bytes |
Indicates the drop bytes for the CoS queue. |
|
Priority Note:
Exception: only supported on VSP 8600 Series. |
Indicates the priority of the queue for the packet going to CP. |
|
Shape Rate (kbps) Note:
Exception: only supported on VSP 8600 Series. |
Indicates the maximum throughput in kbps to CP when a burst occurs . Packets exceeding this limit will be dropped. |
