Displaying the System Uptime

The system uptime refers to the time that the chassis was powered on and has at least one Supervisor
module controlling the switch. The reset command reintializes the system uptime. Non-disruptive
upgrades and switchovers do not reinitialize the system uptime, hence, the system uptime is contiguous
across such upgrades and switchovers.
The kernel uptime refers to the time since the NX-OS software was loaded on the Supervisor module.
The reset and reload commands reinitialize the kernel uptime.
The active supervisor uptime refers to the time since the NX-OS software was loadded on the active
supervisor module. The active supervisor uptime can be lower than the kernel uptime after nondisruptive
switchovers.
You can use the show system uptime command to view the start time of the system, uptime of the kernel,
and the active supervisor.
This example shows how to display the Supervisor uptime:
switch# show system uptime
System start time:
System uptime:
Kernel uptime:
Active supervisor uptime:
