            Description

            WhIle testing IRT in large topologies instability and unexpected non-established connections can be observed, independend from the IRT configuration of SendClock and ReductionRatio.

            In error case the IO Device reports an unexpected diagnosis (e.g. PTCP mismatch, PeerChassisID mismatch, ...).

            Especially in networks with more than 36 netX devices the issue can be observed.
