Field Description
Major Domain Name of the ERPS major domain.
Node ID A MAC address unique to this ring node.
R-APS with VC The R-APS Virtual Channel is the R-APS channel connection used
to tunnel R-APS messages between two interconnection nodes of
a sub-ring in another Ethernet ring or network.
R-APS Def MAC Indicates if the switch’s MAC address is used to identify the node
in R-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receiving outdated R-APS messages.
WTB The wait-to-block timer interval used to delay reversion after a
Forced Switch or Manual Switch has been cleared.
WTR The wait-to-restore timer interval used to verify that the ring has
stabilized before blocking the RPL after recovery from a signal
failure.
