This write-triggered command object clears active alarm indications and resets the chassis's physical alarm relay contacts, with the admin selecting how much to clear -- all alarms, or just minor, major, or critical severity -- and the device resets this object's value to done(0) once the clear operation completes. This is the SNMP equivalent of physically pressing an alarm-cutoff button on the chassis, letting an admin silence alarm contacts (which often drive external annunciators or NOC signaling) without needing local console access. For example, an admin remotely clearing a false critical alarm would write critical(4) to this object, and afterward reading it back would show done(0) confirming the clear completed.
