Syntax Description
Defaults Both the software image and device manager files are downloaded.

The BOOT environment variable is changed to point to the new software image on the flash: file system.
Image names are case sensitive; the image file is provided in tar format.
Command Modes Privileged EXEC
/force-reload Unconditionally force a system reload after successfully downloading the
software image.
/imageonly Download only the software image but not the files associated with the device
manager. The device manager files for the existing version are deleted only if
the existing version is being overwritten or removed.
/leave-old-sw Keep the old software version after a successful download.
/no-set-boot Do not alter the setting of the BOOT environment variable to point to the new
software image after it is successfully downloaded.
/overwrite Overwrite the software image in flash memory with the downloaded image.
/reload Reload the system after successfully downloading the image unless the
configuration has been changed and not been saved.
/safe Keep the current software image; do not delete it to make room for the new
software image before the new image is downloaded. The current image is
deleted after the download.
