Description: An object configuring the registration state of an interface, and indicating its registration state. Write operation changes the registration state to its new value. Read operation returns the value of the state. The registration state is reflected in this object and in the dot3MpcpRegistrationState object. none(1) indicates an unknown state, register(2) indicates a registered LLID, deregister(3) indicates a deregistered LLID, reregister(4) indicates an LLID that is reregistering. The following list describes the operation of the interface, as specified in the [802.3ah], when a write operation is setting a value. none(1) - not doing any action. register(2) - registering an LLID that has been requested for registration (The LLID is in registering mode. dot3MpcpRegistrationState - registering(2) ). deregister(3) - deregisters an LLID that is registered (dot3MpcpRegistrationState - registered(3) ).

reregister(4) - reregister an LLID that is registered (dot3MpcpRegistrationState - registered(3) ). The behavior of an ONU and OLT interfaces, at each one of the detailed operation at each state, is described in the registration state machine of figure 64-22, [802.3ah]. This object is applicable for an OLT and an ONU. At the OLT, it has a distinct value for each virtual interface. The write operation is not restricted in this document and can be done at any time. Changing dot3ExtPkgObjectRegisterAction state can lead to a change in the registration state of the respective interface leading to a deregistration and an interruption of service of the users connected to the respective EPON interface.
