Monitoring and Managing the Switch
A received frame exceeded the Fibre Channel frame maximum size or was less
than the Fibre Channel minimum size, indicating the frame arrived at the switch’s
port corrupted. Frame corruption may be caused by device disconnection, an
optical transceiver failure at the device, a bad fiber-optic cable, or a poor cable
connection.
Troubleshooting Tips
As a general rule, you should clear all counts after the system is stabilized. When
looking at the Performance View, roughly keep track of the time interval when
errors accumulate to judge the presence and severity of a problem. Also,
recognize that there is a link recovery hierarchy implemented in Fibre Channel to
handle some level of “expected anomalies.” In general, only be concerned with
error counts that increment very quickly.
Button Functions
The two buttons located at the right end of the title bar on the Statistics Values table
are:
• Clear
The Clear button clears all counters to zero. Clicking this button displays a Clear
Request Confirmation dialog box. Confirming the request clears the statistics in
the hardware at the physical port. Note that this also clears counters for other
Product Manager users.
An entry identifying when the statistics were cleared and by whom is saved in the
Audit Log.
• Refresh
The Refresh button updates the data in the statistics tables and enables you to
compare values at any given time. Note that you can also refresh data by clicking
the port’s bar graph.
