esaReflectorOperationalState is a read-only OperationalState value representing whether the ESA Reflector is actually up and able to answer test traffic right now. An administrator checks this to distinguish a reflector that is merely configured from one that is genuinely responding to probes. For example, every probe pointed at one reflector reporting total loss, combined with this reflector showing a disabled operational state, tells the technician the reflector itself is down rather than there being twenty separate simultaneous circuit faults.
