Advanced System Diagnostics and Troubleshooting Guide

To detect a reboot loop, a timestamp and a counter are saved. Each time the switch reboots because of a 
software crash or exception, the counter is incremented. A user-executed 

reboot

 command clears the 

timestamp and counter to prevent a false reboot loop protection. This action also allows the user to 
bring the switch out of minimal operation mode so that the system can come up normally after the 
failure has been identified and fixed.

To bring a switch out of minimal operation mode, perform these steps:

Begin collecting background information that might help isolate the causes of the problem and 
contact Extreme Networks technical support and notify them about the problem.

Note any recent hardware or configuration changes.

Create a detailed description of all the known symptoms.

Capture the output from the 

show log

 command.

Capture the output from the 

show diagnostics

 command.

On a sheet of paper, write down the state of all LEDs on the switch.

Use the 

clear log diag-status

 command to clear the hardware error codes.

Use the 

reboot

 command to reboot the system.

Use the show tech CLI command to collect system information.

Send all of the information about the problem to Extreme Networks technical support.
