esaProbeAdminState is a read-only AdminState value representing the ESA Probe's administrative state, and the description explicitly notes it is not externally managed (i.e. it cannot be set directly via SNMP, only observed). An administrator reads it to see the probe's intended operating state as maintained internally by the device rather than as a direct configuration knob. For example, a management application polls this alongside esaProbeOperationalState to confirm that a probe the administrator intended to be active has actually reached that administrative state after being created.
