Description: Huawei ERPS (Ethernet Ring Protection Switching, G.8032) MIB for managing ring topology protection and switchover on Ethernet ring networks.

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 HUAWEI-ERPS-MIB?

HUAWEI-ERPS-MIB is a Huawei enterprise MIB for managing Ethernet Ring Protection Switching (ITU-T G.8032) on Ethernet ring network topologies. It exposes configuration and status data for ring protection instances, including ring nodes, protection switching state, and ring port roles. This MIB supports monitoring the software-level fault-protection status of the Ethernet ring, such as whether a ring is in an idle, protection, or failed state, which directly reflects the health of the ring topology and its ability to reroute traffic around a fault. It builds on the ITU-T G.8032 ERPS standard that defines the ring protection protocol it manages. It is deployed on Huawei datacom switches and routers participating in Ethernet ring topologies in metro and enterprise networks requiring sub-50ms failover. Engineers can download the HUAWEI-ERPS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-ERPS-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

Huawei datacom switch
Huawei Ethernet ring switch/router

Monitoring Examples

An administrator would monitor the ERPS ring status objects to confirm a ring is in its normal idle state with no active protection switching, since a ring stuck in protection state would indicate an unresolved link or node failure on the ring. No sample_objects were provided in the source, so specific table names are inferred from the module's stated ERPS scope rather than confirmed directly.

What Can Be Monitored

ring protection switching state
ring port role
ring topology health
G.8032 protection status

How to Use in IPNetwork Monitor

Example using hwRxRapsSfPktCnt OID:

Select a Huawei datacom switch/router (Ethernet Ring Protection Switching, ITU-T G.8032) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hwRxRapsSfPktCnt into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of received RAPS SF packets. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
