tmnxOamBfdOnLspPingReturnCode

A value of type TmnxOamPingRtnCode is an enumerated integer that
indicates the return code received in the OAM ping response common
header.
          
Code points:
   notApplicable       The return code has no significance in the
                       context of the test being conducted.
   fecEgress           Replying router is an egress for the Forwarding
                       Equivalence Class (FEC).
   fecNoMap            Replying router has no mapping for the FEC.
   notDownstream       Replying router is not one of the
                       downstream routers.
   downstream          Replying router is one of the downstream
                       routers and its mapping for this FEC on the
                       received interface is the given label.
   downstreamNotLabel  Replying router is one of the downstream
                       routers but its mapping for this FEC is not
                       the given label.
   downstreamNotMac    Replying router is one of the downstream
                       routers but it does not have the given MAC
                       address
   downstreamNotMacFlood   Replying router is one of the downstream
                       routers but it does not have the given MAC
                       address and is unable to flood the request.
   malformedEchoRequest    A malformed echo request was received.
   tlvNotUnderstood    One or more of the TLVs was not understood.
   downstreamNotInMfib Replying router is one of the downstream
                       routers but it does not have an MFIB entry
                       for the given source group combination.
   downstreamMismatched    Downstream mapping mismatched.
   upstreamIfIdUnkn    Upstream interface index unknown.
   noMplsFwd           Label switched but no MPLS forwarding at
                       stack-depth.
   noLabelAtStackDepth No label entry at stack-depth.
   protoIntfMismatched Protocol not associated with interface at
                       FEC stack-depth.
   terminatedByOneLabel    Premature termination of ping due to
                       label stack shrinking to a single label.
   seeDDMapForRetCodeSubCode   See DDMap TLV for rc and sub-rc.
   fecStackChange      Label switched with FEC stack change.
