This object reports the beginning of the static label range that is actually in effect right now, as opposed to the administratively configured value that may be pending a reboot. An admin compares this against cienaCesMplsStaticAdminLabelRangeStart to confirm whether a recent configuration change has actually taken hold yet, since the administrative object alone won't reflect reality until the required reboot happens. For example, seeing this operational value still showing the old range after changing the admin value confirms the pending reboot hasn't occurred yet.
