TimeProvider 5000 CLI Command Set
Level : User, Config, and Admin
set image
Use this command to provision the module firmware image from which to boot. The
backup image is the inactive (non-boot) image.
Note: Each image has it's own set of configuration data. If Image 1 is
set as the boot image, the configuration data for Image 1 is applied
when the TP 5000 is rebooted. If Image 2 is set as the boot image,
the configuration data for Image 2 is applied when the TP 5000 is
rebooted.
A firmware upgrade is applied to the backup image, and the backup
image is set to be the next boot image. The TP 5000 copies the
currently running configuration data to the data used with the next
boot. Therefore, the configuration should be the same after rebooting,
except for changes due to differences in supported configuration
items between firmware revisions..
Command Syntax:
