Description: Manages IEEE 802.1ag Connectivity Fault Management (CFM) OAM on Ciena CES switches.

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 CIENA-CES-CFM-MIB?

CIENA-CES-CFM-MIB is a Ciena enterprise MIB that instruments IEEE 802.1ag Connectivity Fault Management (CFM) Operations, Administration and Maintenance (OAM) on Ciena Carrier Ethernet Switch (CES) platforms. It exposes fault, configuration, and statistical data related to Continuity Check Messages (CCM), loopback/linktrace exchanges, and service-level fault reporting between Maintenance End Points (MEPs). Its primary monitoring value is software/protocol health rather than physical hardware: operators use it to track CCM error counters, dropped or malformed CCM frames, frame-loss measurements, and active service faults, which together reveal whether Ethernet OAM sessions are healthy or a link/service has silently failed. It builds on the IEEE 802.1ag CFM standard and is typically used alongside other Ciena CES MIBs (RAPS, LAG, OAM) for end-to-end Carrier Ethernet fault management. It is deployed in service-provider and enterprise Carrier Ethernet networks where CES switches provide Layer 2 transport and rapid fault detection is required for SLA compliance. Engineers can download the CIENA-CES-CFM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CIENA-CES-CFM-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.

  • Ciena Carrier Ethernet Switch (CES)

Monitoring Examples

An operator would poll cienaCesCfmGlobalCCMStatsRxTotalErrorCCM and cienaCesCfmGlobalCCMStatsRxTotalMalformedCCM to detect CFM protocol problems, and cienaCesCfmGlobalCCMStatsRxDropCCMBlockedbyOppMep or cienaCesCfmGlobalCCMStatsRxDropCCMServiceDisabled to see why CCMs are being discarded. A rising cienaCesCfmFrameLossMsgFrameLossFar value combined with a populated cienaCesCfmServiceFaultDesc/cienaCesCfmServiceFaultMep pair indicates a specific MEP is experiencing frame loss or a service fault that should trigger a trap-driven alert. These counters let an admin distinguish a genuine link failure from a misconfigured or leaking CFM domain.

What Can Be Monitored

  • CCM error/malformed frame counts
  • dropped CCM reasons (admin disable, blocked by opposite MEP, leakage)
  • far-end frame loss measurements
  • active service fault descriptions
  • MEP fault status
  • CFM protocol health
