This reports the current state of this pseudowire's bandwidth reservation lifecycle -- for example none(1) if no bandwidth has been requested, configured(2) if a value has been set but not yet processed, notRequired(3) if the PW doesn't need a bandwidth reservation at all, or admitted(4) if the requested bandwidth has been successfully accepted and reserved by the underlying tunnel's admission control. This state machine tells an admin exactly where in the reservation process a pseudowire's bandwidth request currently sits, which is especially useful when a PW's configured bandwidth doesn't seem to be reflected operationally -- checking this state clarifies whether the request was rejected, is still pending, or was never actually required in the first place. A pseudowire stuck showing configured(2) rather than progressing to admitted(4) suggests the underlying tunnel doesn't have enough unreserved capacity to admit the requested bandwidth.
