When the value of tmnxOamPingCtlLocalSdp is 'true', the 'svcPing' test
determines an egress SDP-ID that is bound to the service that has
the far-end IP address specified in tmnxOamPingCtlTgtAddress
assigned to it. The far-end address of the specified SDP-ID is
the expected responder-id within the OAM Echo reply message. The
SDP-ID defines the encapsulation of the SDP tunnel encapsulation
used to reach the far-end. This can be IP/GRE or MPLS. On the
originator egress, the Service-ID must have an associated VC-Label
to reach the far-end address of the SDP-ID and the SDP-ID must be
operational for the message to be sent.
This object is optional and valid only when tmnxOamPingCtlTestMode is
equal to 'svcPing'.
