This object reports the operational status of either the redundant master primary port or the redundant responder port associated with this entry (as specified by erptrDprLinkType). A value of redundancyNotOperational(1) indicates that redundancy is not operational on the link associated with this entry. A value of masterPrimaryActive(2) indicates: - redundancy is operational on the link associated with this entry. - the port specified by erptrDprLinkGroupIndex and erptrDprLinkPortIndex is configured as a master port on the primary segment of the redundant link associated with this entry. - the primary segment of the dual-redundant link is currently the active link. - No link failures are currently detected on the primary link. A value of masterPrimaryStandby(3) indicates: - redundancy is operational on the link associated with this entry. - the port specified by erptrDprLinkGroupIndex and erptrDprLinkPortIndex is configured as a master port on the primary segment of the redundant link associated with this entry. - the primary segment of the dual-redundant link is currently the standby link. - No link failures are currently detected on the primary link. A value of masterPrimaryLinkFailure(4) indicates: - redundancy is operational on the link associated with this entry. - the port specified by erptrDprLinkGroupIndex and erptrDprLinkPortIndex is configured as a master port on the primary segment of the redundant link associated with this entry. - a link failure condition exists on the primary segment of the dual-redundant link (which may have caused a fail-over to the secondary link). A value of responderOk(5) indicates: - redundancy is operational on the link associated with this entry. - the port specified by erptrDprLinkGroupIndex and erptrDprLinkPortIndex is configured as a redundant responder port which may be connected to either the primary or the secondary segment of the redundant link associated with this entry. - the redundant responder port has not detected any link failures on the segment to which it is connected. A value of responderLinkFailure(6) indicates: - redundancy is operational on the link associated with this entry. - the port specified by erptrDprLinkGroupIndex and erptrDprLinkPortIndex is configured as a redundant responder port which may be connected to either the primary or the secondary segment of the redundant link associated with this entry. - the redundant responder port has detected a link failure on the segment to which it is connected.
