cienaCesOamLoopbackStatus

The loopback status of the OAM entity.  This status is
determined by a combination of the local parser and
multiplexer states, the remote parser and multiplexer states,
as well as by the actions of the local OAM client.  When
operating in normal mode with no loopback in progress, the
status reads noLoopback(1).  
                              
If the OAM client has sent a Loopback OAMPDU and is waiting
for a response, where the local parser and multiplexer states
are DISCARD (see [802.3ah, 57.2.11.1]), the status is
'initiatingLoopback'.  In this case, the local OAM entity has
yet to receive any acknowledgement that the remote OAM entity
has received its loopback command request.  
                              
If the local OAM client knows that the remote OAM entity is in
loopback mode (via the remote state information as described
in [802.3ah, 57.2.11.1, 30.3.6.1.15]), the status is remoteLoopback(3).  
 If the local OAM client is in the process
of terminating the remote loopback [802.3ah, 57.2.11.3,
30.3.6.1.14], with its local multiplexer and parser states in
DISCARD, the status is terminatingLoopback(4).  If the remote
OAM client has put the local OAM entity in loopback mode as
indicated by its local parser state, the status is
localLoopback(5).  
              
The unknown(6) status indicates the parser and multiplexer
combination is unexpected.  This status may be returned if the
OAM loopback is in a transition state but should not persist. 
              
The values of this attribute correspond to the following
values of the local and remote parser and multiplexer states.
