Minimal Operation Mode
Advanced System Diagnostics and Troubleshooting Guide 113
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.

1 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.
