Figure 6-116. NSF Summary • Admin Status - Select the administrative mode for the interface. When enabled, the stack selects a backup unit to receive checkpointed data from applications on the management unit. • Operation Status - Indicates whether NSF is operational on the stack, which may differ from the Admin Status setting. If a unit that does not support NSF is connected to the stack, then NSF is disabled on all stack members. When 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. The possible values are: - Power-On - The switch re-booted. This could have been caused by a power cycle or an administrative "Reload" command. - Administrative Move - The administrator issued a command for the stand-by manager to take over. - Warm-Auto-Restart - The primary management card restarted due to a failure, and the system executed a nonstop forwarding failover. - Cold-Auto-Restart - 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. • Time Since Last Restart - Time since the current management card became the active management card. For the backup management unit, the value is set to 0d 00:00:00. • Restart In Progress - Indicates whether a restart is in progress. A restart is not considered complete until all hardware tables have been fully reconciled. • Warm Restart Ready - Indicates whether the initial full checkpoint has finished.
