What Is DNOS-METRO-DOT1AG-PRIVATE-MIB?
DNOS-METRO-DOT1AG-PRIVATE-MIB is a Broadcom private MIB for Dell Networking OS (DNOS) devices implementing IEEE 802.1ag Connectivity Fault Management (CFM), used for metro/carrier Ethernet service-level fault detection between maintenance endpoints (MEPs). It extends the standard 802.1ag data model with remote-MEP status objects, letting an admin see the state of continuity-check sessions between endpoints within a maintenance association. Its core use is fault/status monitoring of Ethernet service connectivity: detecting loss of continuity, remote MEP defects, or an unexpected/missing remote MEP identifier indicates a service-affecting fault in the metro Ethernet path, which is critical for SLA-driven carrier Ethernet monitoring. It builds directly on the standard IEEE 802.1ag CFM model and typically coexists with the standards-based DOT1AG-CFM-MIB for the base MEP/MA/MD hierarchy. It is deployed on Dell Networking switches/routers running DNOS in metro Ethernet or carrier Ethernet service deployments. Engineers can download the DNOS-METRO-DOT1AG-PRIVATE-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in DNOS-METRO-DOT1AG-PRIVATE-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
- Dell Networking switch/router running DNOS
Monitoring Examples
agentDot1agRMepTable exposes per-remote-MEP status within a maintenance association, letting an admin verify that all expected remote maintenance endpoints are reachable and reporting continuity-check messages. A remote MEP entry disappearing from this table, or showing a fault/defect state, indicates a break in the Ethernet service path between two endpoints - a key alarm condition for metro Ethernet SLA monitoring. Only agentDot1agRMepTable was provided as a sample object, so companion tables such as local-MEP or MD/MA configuration likely follow the same 802.1ag naming pattern but are not confirmed here.
What Can Be Monitored
- remote MEP continuity status
- remote MEP presence/identifier
- CFM fault/defect state per maintenance association
