Description: Enterasys Networks proprietary extension to the IEEE 802.1ag CFM MIB for Ethernet connectivity fault management.

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 ENTERASYS-IEEE8021-CFM-EXT-MIB?

This is an Enterasys Networks (later Extreme Networks) proprietary enterprise MIB that extends the standard IEEE8021-CFM-MIB, adding vendor-specific objects for IEEE 802.1ag Connectivity Fault Management (CFM) on Enterasys switches. It exposes data organized around CFM memory-pool usage and Maintenance End Point (MEP) diagnostic/syslog behavior, layered on top of the base CFM maintenance domain/association model. The MIB is explicitly geared toward monitoring the software health of the CFM subsystem: memory pool size, in-use memory, and high-water-mark counters reveal resource exhaustion or leaks in the CFM engine, while MEP-level syslog trigger objects (defect priority, fault-notification-generator state) reflect fault status of individual Ethernet OAM endpoints. As an 'EXT' module it depends directly on the standard IEEE8021-CFM-MIB for its core objects and only supplements it with Enterasys-specific behavior. It is deployed on Enterasys/Extreme Ethernet switches and routers running 802.1ag CFM in carrier-grade or enterprise Ethernet networks where connectivity fault detection matters. Engineers can download the ENTERASYS-IEEE8021-CFM-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-IEEE8021-CFM-EXT-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

An administrator would poll etsysIeee8021CfmExtMemPoolTable (indexed by etsysIeee8021CfmExtMemPoolIndex) to track etsysIeee8021CfmExtMemPoolInUse against etsysIeee8021CfmExtMemPoolHighWaterMark, flagging a CFM memory leak if usage climbs toward the pool size without recovering. Separately, etsysIeee8021CfmExtMepTable exposes etsysIeee8021CfmExtMepHighestPrDefectSyslog and etsysIeee8021CfmExtMepFngStateSyslog, letting an operator confirm that a MEP's fault notification generator has escalated a defect to syslog, indicating a connectivity fault on that maintenance endpoint. These extension objects only make sense read alongside the base IEEE8021-CFM-MIB tables they augment.

How to Use in IPNetwork Monitor

Example using etsysIeee8021CfmExtRxDiscardCount OID:

Select an Enterasys Networks switch (legacy, later Extreme Networks) (802.1ag CFM extensions) 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 etsysIeee8021CfmExtRxDiscardCount 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 CFM frames received and discarded since the last reboot. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
