This read-write {on(1), off(0)} object triggers a reboot of the CMM-III only when its own internal logic determines one is required, most likely after a configuration change that cannot take effect without a restart, based on its name and enumeration; the MIB text for this particular object gives no further detail. An admin would use it to apply pending settings without forcing an unnecessary full reboot if none is actually needed. For example, after changing several port configuration objects, an operator could set rebootIfRequired to on(1) and let the unit decide for itself whether a restart is warranted.
