Writing reboot(1) to this object issues a SET command that immediately reboots the CDD-564 unit. The description explicitly warns the reboot happens without saving the configuration to flash, so any unsaved changes (like a pending frequency retune) are lost on restart unless cdd564SaveParamToFlash was set first, a distinction that matters when an admin is trying to apply a change versus just power-cycling a hung unit. If the router's Ethernet forwarding appears wedged (packet counters stuck at zero despite traffic), an admin might SET this object to 1 as a quick remote recovery step, accepting that any un-saved config from that session will be discarded.
