This is a SET-only command that reloads the configuration from the parameter file already stored in flash, discarding whatever changes are currently active in the running configuration. It's the 'undo my in-progress edits' button: if an admin has been experimenting with cdd564RxFEC or cdd564RxCodeRate values live on the unit without saving them, writing reload(1) instantly reverts those unsaved changes back to the last-saved flash state without requiring a full reboot. For example, after test-setting the demodulation type and finding the link won't lock, an admin can SET this object to 1 to snap the demodulator settings back to the previously-saved, working configuration in one step.
