request system shutdown (halt | power-off | reboot)
Statement introduced in Junos OS Evolved Release 18.3R1.
Halt, power-off, or reboot the entire system.
halt instructs the hardware to stop all CPU functions but leaves the system in a powered-on state. This usually means someone has to shut down the machine manually by pressing the power button afterwards.
poweroff stops the CPU but also sends an ACPI hardware signal which instructs the system to commence with a complete and immediate shutdown. This is roughly equivalent to pressing the power button on a typical desktop computer.
reboot reboots the system.
