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 RAISECOM-ELPS-MIB?

RAISECOM-ELPS-MIB is a Raisecom vendor MIB that manages Ethernet Linear Protection Switching (ITU-T G.8031) on Raisecom carrier/metro Ethernet equipment, a mechanism providing fast (sub-50ms) failover between a working and a protection Ethernet path. It exposes configuration and status for ELPS protection groups, typically including the working/protection path identifiers, protection mode (1+1 or 1:1), switching request type, and the current active path/switch state of each group. This is a fault-tolerance/link-health monitoring MIB: it confirms which path (working or protection) is currently active for a protected service, and an unexpected or frequent switchover indicates a failing fiber link, port, or signal-degrade condition on the working path. It directly implements the ITU-T G.8031 standard and typically interacts with underlying Ethernet OAM (802.1ag/Y.1731) fault-detection mechanisms that trigger the switchover. It is typically deployed on Raisecom metro Ethernet switches and media converters providing carrier-grade protected Ethernet services. Network engineers evaluating or troubleshooting this functionality can download the RAISECOM-ELPS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RAISECOM-ELPS-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

Raisecom metro/carrier Ethernet switch
Raisecom media converter/access device supporting ITU-T G.8031

Monitoring Examples

No specific object or table names were captured for this MIB in the available data, so a fully concrete polling example can't be given with certainty; in general an operator would expect to check a protection-group table's active-path/switch-state object to confirm traffic is currently riding the working path, and watch for switchover events indicating the working path failed over to protection. This kind of check is typically triggered by an Ethernet OAM continuity-check failure on the working link.

What Can Be Monitored

ELPS protection group active path (working vs protection)
protection switching state/events
protection mode configuration (1+1 / 1:1)
