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.
