dot3OamLoopbackStatus

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).
              
The values initiatingLoopback(2) and terminatingLoopback(4)
can be read or written.  The other values can only be read -
they can never be written.  Writing initiatingLoopback causes
the local OAM entity to start the loopback process with its
peer.  This value can only be written when the status is
noLoopback(1).  Writing the value initiatingLoopback(2) in any
other state has no effect.  When in remoteLoopback(3), writing
terminatingLoopback(4) causes the local OAM entity to initiate
the termination of the loopback state.  Writing
terminatingLoopack(4) in any other state has no effect.
              
If the OAM client initiates a loopback and 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
acknowledgment 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 that 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.
