This reports the administratively configured starting label value of the static MPLS label range -- the lower boundary of the block of labels reserved for manually assigned (static) LSPs on this device -- and per the MIB, any change to this boundary only takes effect after the device is rebooted. Static and dynamic label ranges must never overlap, so an admin sizing capacity for manually provisioned pseudowires or tunnels needs to know exactly where the static-admin block begins to avoid label collisions when planning new static LSPs. If this value reports 16, the static administrative range starts at the very bottom of the usable label space, leaving everything above it up to some configured end value for static assignments.
