            Description

            WhIle testing IRT in large topologies instability and unexpected non-established connections can be observed.

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

            In error case the RTC3PSM state of the IO Device reported to the neighbor via LLDP may be wrong (UP) altough internal RTC3PSM state is RUN (which is reported via SNMP or Profinet records).

            The detailed circumstances under which the issue occurs is not yet clear. Especially in networks with more than 32 netX devices the issue can be observed.

            Currently the issue has only been confirmed for netX51. Reproducability for other chips is currently in investigation.
