Usage Guidelines

Usage Scenario

When diagnosing faults on an interface, run the display counters interface [ interface-type interface-number ] [ verbose | nonzero ] command to view detailed information about packets received and sent by the interface to determine whether the interface works properly. You can also run this command to view detailed traffic statistics on an interface, including typical packet statistics and number of packets discarded in queues. You can also run this command to view non-zero traffic statistics on an interface, including typical packet statistics and number of packets discarded in queues.

Follow-up Procedure

If you want to collect new traffic statistics, run the reset counters interface command to clear the current statistics.

Example
