Excessive Port Errors

The switch can monitor a set of port errors and generate alarms based on

user-defined sample windows and thresholds. These port errors include the

following:

Cyclic redundancy check (CRC) errors

Decode errors

ISL connection count

Device login errors

Device logout errors

Loss-of-signal errors

Port threshold alarm monitoring is disabled by default. For information about

managing port threshold alarms, refer to the QLogic 5800V Series Fibre Channel

Switch Command Line Interface Guide.

If the count for any of these errors exceeds the rising trigger for three consecutive

sample windows, the switch generates an alarm, disables the affected port, and

changes the port 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 adapter

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, and 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 QLogic 5800V 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.
