Description: Manages ZTE access node Connectivity Fault Management (CFM) including MEPs, MAs, and continuity checks.

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 ZTE-AN-CFM2-MIB?

This is ZTE's private MIB implementing Connectivity Fault Management (CFM) per IEEE 802.1ag and ITU-T Y.1731 for its access node product line, used to detect Ethernet-layer connectivity faults across a carrier network. It exposes configuration for Maintenance Endpoints (MEPs) and Maintenance Associations (MAs) along with the continuity-check and fault-detection results between them. Its monitoring emphasis is squarely on fault detection: loss-of-continuity and remote-defect conditions between MEPs surface network-path faults, essentially functioning as a software-level early-warning system for connectivity problems rather than reporting on hardware sensors like temperature or power. It implements the IEEE 802.1ag/ITU-T Y.1731 CFM standards and typically coexists with an access node's underlying bridge/VLAN MIBs. It is deployed on ZTE access and aggregation nodes in carrier Ethernet networks where operators need proactive end-to-end fault detection across the metro/access segment. Engineers can download the ZTE-AN-CFM2-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZTE-AN-CFM2-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

  • ZTE access node
  • carrier Ethernet aggregation switch

Monitoring Examples

No sample object names were provided for this MIB, so specific identifiers can't be cited here. Conceptually, an operator would poll per-MEP/MA continuity-check status to detect a loss-of-continuity or remote-defect condition between two Ethernet maintenance endpoints, revealing a fault in the access/aggregation path before it is reported as a customer-facing service outage.

What Can Be Monitored

  • MEP/MA continuity check status
  • connectivity fault/defect state
  • remote MEP reachability

How to Use in IPNetwork Monitor

Example using zxAnCfm2LMepCciSentCcms OID:

Select a ZTE access node, carrier Ethernet aggregation switch (802.1ag/Y.1731 MEP continuity-check/fault status) 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 zxAnCfm2LMepCciSentCcms 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 total number of CCM packets transmitted. 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.
