Specifies the hop index for an Alcatel 7x50 SR OAM Trace Route hop. Values for this object with respect to the same tmnxOamTrCtlOwnerIndex and tmnxOamTrCtlTestIndex MUST start at 1 and increase monotonically. The tmnxOamTrHopsTable keeps the current Alcatel 7x50 SR OAM Trace Route path per tmnxOamTrCtlEntry if enabled by setting the corresponding tmnxOamTrCtlCreateHopsEntries to true(1). All hops (tmnxOamTrHopsTable entries) in an Alcatel 7x50 SR OAM Trace Route path MUST be updated at the same time when an Alcatel 7x50 SR OAM Trace Route operation completes. Care needs to be applied when either a path changes or can't be determined. The initial portion of the path, up to the first hop change, MUST retain the same tmnxOamTrHopsHopIndex values. The remaining portion of the path SHOULD be assigned new tmnxOamTrHopsHopIndex values.
