Manage Auto-Diagnostics and Clear Events or Problems
Auto-diagnostics consists of the following monitoring options, all of which are enabled by default:
•
Identify blocked ports. The switch can automatically identify a blocked port that is caused by a loop
condition. If this condition occurs, the Power LED lights or blinks solid amber and the icon for the affected
port on the AUTO-DIAGNOSTICS page displays blue. If the condition is resolved, the Power LED is
reset automatically. Regardless of whether the condition is resolved, you can clear the event on the
AUTO-DIAGNOSTICS page and reset the Power LED.
•
Identify ports with CRC error packet events.The switch can automatically identify a CRC error packet
event. If this condition occurs, the Power LED lights or blinks solid amber and the icon for the affected
port on the AUTO-DIAGNOSTICS page displays blue. You can clear the event on the
AUTO-DIAGNOSTICS page and reset the Power LED. This action does not affect the statistics that are
shown in the CRC Error Packets column on the Port Statistics page (see
page 67). However, if you clear the statistic on the Port Statistics page, the event on the
AUTO-DIAGNOSTICS page is also cleared and the Power LED is reset.
•
Identify ports with LAG problems. The switch can automatically identify whether a problem occurs
with a port that is a member of a LAG or whether such a port is shut down. If this condition occurs, the
Power LED lights or blinks solid amber and the icon for the affected port on the AUTO-DIAGNOSTICS
page displays blue. Regardless of whether the condition is resolved, you can clear the event on the
AUTO-DIAGNOSTICS page and reset the Power LED.
•
Identify an unsuccessful firmware update. The switch can automatically identify an unsuccessful
firmware upgrade, including an attempt to load an invalid image. If a power cycle occurs during a firmware
update, a notification does not occur. If an unsuccessful firmware update occurs, the Power LED lights
or blinks solid amber and the FAILED button on the AUTO-DIAGNOSTICS page displays blue. You
can clear the event on the AUTO-DIAGNOSTICS page and reset the Power LED.
You can enable and disable these monitoring options individually.
