Excessive Port Errors

The switch can monitor a set of port errors and generates alarms based on
user-defined sample windows and thresholds. These port errors include the
following:
CRC errors
Decode errors
ISL connection count
Login errors
Logout errors
Loss-of-signal errors
Port threshold alarm monitoring is disabled by default. Refer to the SANbox 1400
Series Switch Management User's Guide for information about managing port
threshold alarms.
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
Fault 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 or the SANsurfer Switch Manager application.
Refer to the
list of the alarm configuration defaults. Are the thresholds and sample
window correct?
