View Port Egress CoS Queue Statistics
View the port egress CoS queue statistics. The system displays the statistics of the forwarded packets and bytes, and the dropped packets and bytes.
About this task
If you disable rate limiting on queue 6, bandwidth is shared based on the weights from queues 0 through 6. Based on equal weights assigned for queues 4 through 6, equal amounts of traffic egress queues 4 through 6. The system displays Queue 6 to provide much lower throughput than 50% of port bandwidth.
Note
If there is egress congestion when you enable the boot config flags flow-control-mode command, then the system does not drop the packets at egress, and does not increment the counters under the show qos cosq-stats interface {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]} command output. Instead, the system drops the packets at the ingress port and the system counts them under the INDISCARD column of show interfaces gigabitEthernet error {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]} command output.
Procedure
- View the port egress
CoS queue statistics:
show qos cosq-stats interface <PT_PORT>
Note
The show command output varies based on your hardware platform. 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.
Variable Definitions
Use the data in the following table to use the show qos cosq-stats interface <PT_PORT> command.
