Parameters
mdc { id | all }: Specifies an MDC by its ID or specifies all MDCs. If you do not specify this option, the command displays stability information for the system.
Usage guidelines
Before performing an ISSU or a switchover, execute this command multiple times to identify whether the system is operating stably. If the value of the System State field is not Stable, you cannot perform an ISSU. If the value of the Redundancy Stable field is not Stable, you cannot perform a switchover.
The system takes some time to start up. If the values of the status fields do not change to Stable, execute this command multiple times to identify the device or a card or MDC that is not in Stable state. You can also use other commands to identify the faulty components.
