Stacking Commands
31
ProSafe Managed Switch
continues to be forwarded in hardware while the management functions initialize on the
backup unit. NSF is enabled by default on platforms that support it. The administrator can
disable NSF to redirect the CPU resources consumed by data checkpointing. If a unit that
does not support NSF is connected to the stack, then NSF is disabled on all stack members.
If a unit that does not support NSF is disconnected from the stack and all other units support
NSF, and NSF is administratively enabled, then NSF operation resumes.

Last Startup Reason
The type of activation that caused the software to start the last time:
• “Power-On” means that the switch rebooted. This could have been caused by a
power cycle or an administrative “Reload” command.
• “Administrative Move” means that the administrator issued the
movemanagement command for the stand-by manager to take over.
• “Warm-Auto-Restart” means that the primary management card restarted due to
a failure, and the system executed a nonstop forwarding failover.
• “Cold-Auto-Restart” means that the system switched from the active manager to
the backup manager and was unable to maintain user data traffic. This is usually
caused by multiple failures occurring close together.
