fastboot
Reboots the control processor (CP), bypassing the power-on self-tests (POST).
Synopsis fastboot
Operands None
Defaults None
Command Modes Privileged EXEC mode
Description Use this command to perform a “cold reboot” (power off and restart) of the control processor,
bypassing POST when the system comes back up. Bypassing POST can reduce boot time
significantly.
Usage Guidelines The fastboot operation is disruptive, and the command prompts for confirmation before executing.
When you reboot a switch connected to a fabric, all traffic to and from that switch stops. All ports
on that switch remain inactive until the switch comes back online.
On a modular chassis, the fastboot commands only reboots the management module on which
the command is executed. If you log in to the switch IP address and execute the fastboot
command, only the active management module reboots and POST is bypassed.
Examples To perform a cold reboot on the switch:
switch# fastboot
Are you sure you want to fastboot the switch [y/n]?: y
