Usage Guidelines

You can use this command to check the type and time of a reset.

This command displays reset information collected by the device, including the reset type and time. The following reset types may be displayed:

MANUAL: The device was restarted manually using the reboot command or the NMS.
POWER: The device restarted after being powered off (usually because users switch off the power supply).
SCHEDU: The device restarted at a scheduled time.
FSP: The device restarted due to a stack split or merge or an incorrect Mod-ID.
EXCEPTION: The device restarted due to an exception or a dead loop.
VRP: The device restarted due to an active/standby switchover or a fault on the VRP platform.
SOFTWARE: The device restarted due to a software fault which is traceable.
OS: The kernel was abnormal and initiated a reset.
WATCHDOG: The device restarted due to the hardware watchdog.
OTHER: Other causes.
- A hardware component, such as the PCU, flash, or memory, has failed.
- The device has overheated.
- The switch was power recycled instantly, for example, when the power cable is in bad contact or when transient overvoltage and loss of voltage occurs. In this case, check whether the power cable is correctly connected to the switch.
- The reboot was caused by other reasons that cannot be categorized into the preceding types. For example, the switch rebooted after joining a stack.
