APS messages.
Propagate TC Shows if the ring is configured to propagate topology change
notification messages.
Non-ERPS Device Protect Shows if the RPL owner node is configured to send non-standard
health-check packets when it enters protection state without any link
down event having been detected through SF messages
Holdoff The hold-off timer interval used to filter out intermittent link faults.
Guard The guard timer interval used to prevent ring nodes from receiving

stabilized before blocking the RPL after recovery from a signal failure.
