Description: Hirschmann HiOS (HM2) Device Level Ring (DLR) redundancy MIB for EtherNet/IP DLR topology management.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is HM2-L2REDUNDANCY-DLR-MIB?

HM2-L2REDUNDANCY-DLR-MIB is a Hirschmann HiOS (HM2) MIB implementing EtherNet/IP Device Level Ring (DLR) redundancy, an industrial-Ethernet ring protocol used to provide fast failover in factory-automation networks. It exposes global admin state, per-ring configuration (ring ports and their interface indices), operational status of ring ports, gateway configuration/status for inter-ring connectivity, and a table of ring participants. Monitoring focuses on the operational health of the ring topology — whether DLR is enabled, whether ring ports are up, and whether the expected set of ring participants is present — which is critical for detecting a broken or degraded ring in industrial control networks before it causes a network partition. It depends on the underlying IF-MIB ifIndex references for its ring port objects, tying DLR ring status to standard interface status. It is deployed on Hirschmann industrial Ethernet switches used in EtherNet/IP-based automation rings. Engineers can download the HM2-L2REDUNDANCY-DLR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HM2-L2REDUNDANCY-DLR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Hirschmann industrial Ethernet switches (HiOS)

Monitoring Examples

An operator can poll hm2DlrStatusTable and hm2DlrRingport1OperStatus/ring port 2 status (via hm2DlrConfigTable, keyed by hm2DlrRingIndex) to confirm both ring ports on a switch are operationally up; one port down while hm2DlrGlobalAdminState remains enabled indicates a ring break being masked by redundancy. hm2DlrRingParticipantsTable can be checked to verify the expected number of switches are seen in the ring, and hm2DlrGatewayStatusTable / hm2DlrMibNotifications would surface a change if the ring's gateway connection to another network segment fails.

What Can Be Monitored

DLR global admin state
ring port 1/2 operational status
ring participant membership
DLR gateway configuration/status
ring redundancy fault notifications
