Displaying Port Counters

The SHOW/MONITOR PORT COUNTERS command displays the counters associated with each of the selected ports. Use this command to discover the source of any problems between the port device and the port. Typically, network problems can be detected with errors recorded in the access server status display.

The maximum value possible for the port counters is 4, 294, 967, 295. If a counter reaches that value, it remains at that value until either the counters are set to zero or the access server is initialized.

Three counters in the port counters display can indicate possible problems. The access server status display gives values for port framing, parity, and overrun errors for the access server. Usually Framing Errors, Parity Errors, and Overrun Errors are zero. If the access server status display indicates nonzero values for any of these errors, you can use the port counters display to find the port or ports that are causing the errors.
