Excessive Port Errors

The switch monitors a set of port errors and generates alarms based on user-defined sample intervals and thresholds. Refer to the SANbox2-8c/16 Switch Management User’s Guide for information about managing alarms. These port errors include the following:

CRC errors

Decode errors

ISL connection count

Login errors

Logout errors

Loss-of-signal errors

If the count for any of these errors exceeds the rising threshold for three consecutive sample intervals, the switch generates an alarm and disables the affected port, changing its operational state to “down”. Port errors can be caused by the following:

Thresholds are too low or the sample interval is too small

Faulty Fibre Channel port cable

Faulty SFP

Faulty port

Fault device or HBA

Review the alarm log to determine if excessive port errors are responsible for disabling the port. Look for a message that mentions one of the monitored error types indicating that the port has been disabled, then do the following:

1.Examine the alarm configuration for the associated error using the Show Config Threshold command or the SANbox Manager application. Refer to the ”Show Config Command” on page B-55. Refer to Table B-4for a list of the alarm configuration defaults. Are the thresholds and sample interval correct?

Yes - Continue

No - Correct the alarm configuration. If the condition remains, continue.
