This object reports whether the dynamic encap tunnel is actually operationally up or down right now, independent of its administrative setting. On a signaled tunnel specifically, an administratively-enabled-but-operationally-down state usually points to a signaling failure -- for example insufficient bandwidth along the path, or an unreachable destination -- rather than a simple configuration mismatch, since the path itself is established dynamically rather than manually defined. For example, finding this tunnel stuck operationally down while administratively enabled would prompt the admin to check the resource reservation referenced by cienaCesMplsDynamicIngressTunnelResourcePointer for a bandwidth shortfall.
