Description: Manages SAGEM radio link protection switching configuration, active/standby path status, and switchover events.

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 PROTECTION-MIB?

PROTECTION-MIB is a vendor MIB from SAGEM covering protection switching mechanisms used in SDH (Synchronous Digital Hierarchy) transmission equipment, applied here to radio link protection. It exposes configuration for protection schemes along with active/standby path status and switchover event notifications. Its monitoring value is centered on fault and redundancy status: administrators can see which path is currently active, whether a protection switchover has occurred, and receive traps when a switchover event happens, which is a direct indicator of a link or hardware fault being handled by the protection mechanism. It is conceptually tied to SDH/SONET protection-switching standards, implying alignment with broader transmission-network fault management conventions even though it is a proprietary implementation. It is deployed on SAGEM microwave/radio link transmission equipment used in telecom backhaul networks. Engineers can download the PROTECTION-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PROTECTION-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.

Monitoring Examples

No sample_objects were provided in the source, so specific object or table names cannot be cited; in general an admin would poll active/standby path status objects to confirm which path is currently carrying traffic and watch for switchover event traps. A switchover event trap firing unexpectedly would indicate a radio link degradation or failure that triggered the protection mechanism. This remains a general description absent concrete identifiers.
