An entry in this table is created when the result of a OAM
'lspTraceRoute' probe is determined. The initial 2
instance identifier index values identify the tmnxOamTrCtlEntry
that a OAM probe result (tmnxOamTrProbeHistoryEntry) belongs
to. The tmnxOamTrProbeHistoryIndex identifies a group of replies
received in response to a specific probe transmission. The fourth
and fifth indexes select the hop and the probe at that hop for a
particular Alcatel-Lucent SROS OAM Trace Route operation.
The tmnxOamLspTrMapIndex selects a single L2 mapping entry
within a specific 'lspTraceRoute' probe reply.
The agent starts assigning tmnxOamLspTrMapIndex values at 1.
