Parameter Description
NSF Administrative Status Whether nonstop forwarding is administratively enabled or disabled. Default: Enabled
NSF Operational Status Indicates whether NSF is enabled on the stack.
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.
Time Since Last Restart Time since the current management unit became the active management unit.
Restart in progress Whether a restart is in progress.
Warm Restart Ready Whether the system is ready to perform a nonstop forwarding failover from the management unit to the backup unit.
Copy of Running Configuration to Backup Unit: Status Whether the running configuration on the backup unit includes all changes made on the management unit. Displays as Current or Stale.
Time Since Last Copy When the running configuration was last copied from the management unit to the backup unit.
Time Until Next Copy The number of seconds until the running configuration will be copied to the backup unit. This line only appears when the running configuration on the backup unit is Stale.
Per Unit Status Parameters
