Last Startup
Reason
The type of activation that caused
the software to start the last time.
There are four options. “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 a 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.
