This object is used to convey to an NMS the state of the policy.
A value of 'up' implies that the policy rule has been pushed to
the QoS / filtering manager (i.e. the PEP). A value of 'down'
means the policy is invalid, so it was not pushed to the
QoS / filtering manager. A value of 'notReady' means this
rule is valid, but not currently active (PVP not active, etc).
