Checking packet statistics on S series switches

For S series fixed switches (except S1700 switches), if rate limiting has been configured in the inbound direction of an interface using the qos lr inbound cir cir-value [ cbs cbs-value ] command, you can run the display qos statistics interface interface-type interface-number inbound command to check packet statistics.
Note: For some S series fixed switches that do not support this command, you can capture packets on interfaces to check packet loss.
If a QoS CAR profile has been applied to a specified VLAN or the inbound direction of an interface on an S series modular switch, you can run the display qos car statistics interface interface-type interface-number inbound or display qos car statistics vlan vlan-id { broadcast-suppression | multicast-suppression | unicast-suppression } command to check statistics on forwarded and discarded packets.
If traffic shaping has been configured on an S series switch using the qos queue queue-index shaping cir cir-value pir pir-value [ cbs cbs-value pbs pbs-value ] command, you can run the display qos queue statistics interface interface-type interface-number [ queue queue-index ] command to check queue-based traffic statistics on an interface.
If rate limiting has been configured through MQC on an S series switch, you can run the display traffic policy statistics command to check packet statistics in the system, or on a specified card, interface, or VLAN to which a traffic policy has been applied.
