Rebooting your switch
CAUTION:
•
Rebooting the switch interrupts network services.
• To avoid configuration loss, use the save command to save the running configuration before a reboot.
• Before a reboot, use the display startup and display boot-loader commands to verify whether you have
specified the correct startup configuration file and startup software images.
You can reboot the switch in one of the following ways:
• Power off and then power on the device. This method might cause data loss, and is the
least-preferred method.
• Reboot the switch immediately at the CLI.
• At the CLI, schedule a reboot to occur at a specific time and date or after a delay.
The first method is called "cold reboot" or "cold startup". The second and third methods are called
"warm reboot" or "warm startup", and can be used remotely.
For data security, if you reboot the switch while the switch is performing file operations, the switch does
not reboot.
The precision of the rebooting timer is 1 minute. One minute before the rebooting time, the switch
prompts "REBOOT IN ONE MINUTE" and reboots in one minute.
To reboot cards or switches immediately at the CLI:
Task Command Remarks
In standalone mode, reboot a
card or the switch immediately.
reboot [ slot slot-number ]
Available in user view.
If you reboot the active MPU or do not
specify the slot keyword, the reboot
command reboots the switch.
In IRF mode, reboot an IRF
member switch, a card on the
switch, or all IRF member
switches.
reboot [ chassis chassis-number
[ slot slot-number ] ]
Available in user view.
If you reboot the active MPU or do not
specify the slot keyword, the reboot
command reboots the member switch.
To schedule a reboot:
Task Command Remarks
Specify the reboot date and
time.
schedule reboot at hh:mm [ date ]
Available in user view.
By default, the scheduled reboot
function is disabled.
