If the count for any of these errors exceeds the rising trigger for three consecutive 
sample windows, the switch generates an alarm and disables the affected port, 
changing its operational state to “down”. Port errors can be caused by the 
following:
„
Triggers are too low or the sample window is too small
„
Faulty Fibre Channel port cable
„
Faulty SFP
„
Faulty port
„
Faulty device or HBA
Review the event browser 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. Refer to the Show Config Threshold command 
in the SANbox 5000 Series Fibre Channel Switch Command Line Interface 
Guide
. Are the thresholds and sample window correct?
„
Yes - Continue
„
No - Correct the alarm configuration. If the condition remains, continue.
2.
Reset the port, then perform an external port loopback test to validate the 
port and the SFP. Refer to the SANbox 5000 Series Fibre Channel Switch 
Command Line Interface Guide
 for information about testing ports. Does the 
port pass the test?
„
Yes - Continue
„
No - Replace the SFP and repeat the test. If the port does not pass the 
test, contact your authorized maintenance provider. Otherwise 
continue.
3.
Replace the Fibre Channel port cable. Is the problem corrected?
„
Yes - Complete.
„
No - Continue.
4.
Inspect the device to which the affected port is connected and confirm that 
the device and its HBA are working properly. Make repairs and corrections 
as needed. If the condition remains, contact your authorized maintenance 
provider.
