Excessive Port Errors
59021-06 A
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:
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:
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.
CRC errors
Decode errors
ISL connection count
Login errors
Logout errors
Loss-of-signal errors
Thresholds are too low or the sample interval is too small
Faulty Fibre Channel port cable
Faulty SFP
Faulty port
Fault device or HBA
Examine the alarm configuration for the associated error using the Show
Config Threshold command or the SANbox Manager application. Refer to
the
the alarm configuration defaults. Are the thresholds and sample interval
correct?
”Show Config Command” on page
Yes - Continue
No - Correct the alarm configuration. If the condition remains, continue.
