Table 102: CLI Request System Halt Command Options (continued)

DescriptionOption

Time at which to stop the software processes on the router. You can specify time in

one of the following ways:

■now—Stops the software processes immediately. This is the default.

■+minutes—Stops the software processes in the number of minutes from now that

you specify.

■yymmddhhmm—Stops the software processes at the absolute time you specify.

Enter the year, month, day, hour (in 24-hour format), and minute.

■hh:mm—Stops the software processes at the absolute time that you specify, on

the current day. Enter the time in 24-hour format, using a colon (:) to separate

hours from minutes.

at time

Specifies the number of minutes from now to stop the software processes on the router.

This option is a synonym for the at +minutes option.

in minutes

Specifies the boot device to boot the router from after the halt:

■compact-flash—Reboots from the internal compact flash. This is the default.

■removable-compact-flash—Reboots from the optional external compact flash. This

option is available on J2320, J2350, J4300, and J6300 Services Routers only.

■usb—Reboots from the USB storage device.

media type

Provides a message to display to all system users before the software processes on the

router are stopped.
