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.
