Source data warning: The official manual's detailed object table explicitly states this OID; the companion MIB declares the same numeric value. The manual's overview tree inconsistently prints 1.3.6.1.4.1.278.1.109 instead of 1.3.6.1.4.1.278.109. No alternate numeric paths are inferred from that diagram.
