Each row in tmnxOamMcastTrCtlTable contains the multicast-trace-route-
specific configuration information needed to launch a multicast trace
route test. The rest of the configuration information needed to
launch the test resides in the corresponding row of tmnxOamTrCtlTable.
Results of multicast trace route tests are stored in
tmnxOamTrResultsTable, tmnxOamTrProbeHistoryTable, and
tmnxOamMcastTrRespTable.
