Description: IEEE 802.1 MIB for Connectivity Fault Management (CFM/802.1ag) providing OAM maintenance domain and MEP 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 IEEE8021-CFM-MIB?
IEEE8021-CFM-MIB is the vendor-neutral IEEE 802.1 standards MIB implementing Connectivity Fault Management (CFM, IEEE 802.1ag) for Carrier Ethernet OAM, used to detect, verify, and isolate connectivity faults across bridged/VLAN networks. It exposes configuration and status data for Maintenance Domains, Maintenance Associations, and Maintenance association End Points (MEPs), including how MEPs stack against interfaces and VLANs. It supports software/protocol status monitoring: via the CFM stack table an operator can see which MEP is active on a given interface/VLAN combination, and receive fault notifications when a MEP loses continuity with its peers, though it does not cover physical sensors like temperature or power. It depends on the base IEEE 802.1Q bridge/VLAN model and typically works alongside IF-MIB (via ifIndex references in the stack table) for interface correlation. It's deployed on Carrier Ethernet switches and bridges in provider and enterprise networks that use CFM for service-level OAM. Network engineers who search for an ieee8021-cfm-mib download usually want the module definition itself so they can compile CFM fault-management support into their NMS or SNMP agent tooling.
IPNetwork Monitor allows you to monitor SNMP objects defined in IEEE8021-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.
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- Carrier Ethernet switches/bridges supporting IEEE 802.1ag CFM
Monitoring Examples
An operator can poll dot1agCfmStackTable/dot1agCfmStackEntry (indexed by dot1agCfmStackifIndex and dot1agCfmStackVlanIdOrNone) to see which MEPs (dot1agCfmStackMepId, dot1agCfmStackMacAddress) are stacked on which interface and maintenance domain level (dot1agCfmStackMdLevel), and watch for a MEP disappearing from the table or a dot1agNotifications trap firing, which signals a lost continuity check / connectivity fault between MEPs. The dot1agCfmVlanTable further confirms which VLANs have CFM instances associated with a maintenance association.
What Can Be Monitored
- MEP stack per interface/VLAN
- MEP MAC address and ID
- maintenance domain level
- CFM connectivity fault notifications
- VLAN-to-maintenance-association mapping

| dot1agCfmDefaultMdTable | 1.3.111.2.802.1.1.8.1.2.4 | not-accessible | For each Bridge component, the Default MD Level Managed Object controls MHF creation for VIDs that are not attached to a specific Maintenance Association Managed Object, and Sender ID TLV transmission by those MHFs. For each Bridge Port, and for each VLAN ID whose data can pass through that Bridge Port, an entry in this table is used by the algorithm in 22.2.3 only if there is no entry in the Maintenance Association table defining an MA for the same VLAN ID and MD Level as this table's entry, and on which MA an Up MEP is defined. If there exists such an MA, that MA's objects are used by the algorithm in 22.2.3 in place of this table entry's objects. The agent maintains the value of dot1agCfmDefaultMdStatus to indicate whether this entry is overridden by an MA. When first initialized, the agent creates this table automatically with entries for all VLAN IDs, with the default values specified for each object. After this initialization, the writable objects in this table need to be persistent upon reboot or restart of a device. **NOTE: this object is deprecated due to re-indexing of the table. | |
| NTF dot1agCfmFaultAlarm | 1.3.111.2.802.1.1.8.0.1 | A MEP has a persistent defect condition. A notification (fault alarm) is sent to the management entity with the OID of the MEP that has detected the fault. Whenever a MEP has a persistent defect, it may or may not generate a Fault Alarm to warn the system administrator of the problem, as controlled by the MEP Fault Notification Generator State Machine and associated Managed Objects. Only the highest-priority defect, as shown in Table 20-1, is reported in the Fault Alarm. If a defect with a higher priority is raised after a Fault Alarm has been issued, another Fault Alarm is issued. The management entity receiving the notification can identify the system from the network source address of the notification, and can identify the MEP reporting the defect by the indices in the OID of the dot1agCfmMepHighestPrDefect variable in the notification: dot1agCfmMdIndex - Also the index of the MEP's Maintenance Domain table entry (dot1agCfmMdTable). dot1agCfmMaIndex - Also an index (with the MD table index) of the MEP's Maintenance Association network table entry (dot1agCfmMaNetTable), and (with the MD table index and component ID) of the MEP's MA component table entry (dot1agCfmMaCompTable). dot1agCfmMepIdentifier - MEP Identifier and final index into the MEP table (dot1agCfmMepTable). | ||

All columns MUST have a valid value before a row can be activated. **NOTE: this object is deprecated due to re-indexing of the table. |
| dot1agCfmMaCompTable | 1.3.111.2.802.1.1.8.1.6.2 | not-accessible | The Maintenance Association table. Each row in the table represents an MA. An MA is a set of MEPs, each configured with a single service instance. This is the part of the complete MA table that is variable across the Bridges in a Maintenance Domain, or across the components of a single Bridge. That part of the MA table that is constant across the Bridges and their components in a Maintenance Domain is contained in the dot1agCfmMaNetTable. This table uses three indices, first index is the Dot1agCfmPbbComponentIdentifier that identifies the component within the Bridge for which the information in the dot1agCfmMaCompEntry applies. The second is the index of the Maintenance Domain table. The third index is the same as the index of the dot1agCfmMaNetEntry for the same MA. The writable objects in this table need to be persistent upon reboot or restart of a device. **NOTE: this object is deprecated due to re-indexing of the table. | |
| dot1agCfmMaGroup | 1.3.111.2.802.1.1.8.2.2.6 | Objects for the MA group. | ||

| dot1agCfmMaMepListEntry | 1.3.111.2.802.1.1.8.1.6.3.1 | not-accessible | The known MEPS table entry. | |
| DOT dot1agCfmMaMepListIdentifier | 1.3.111.2.802.1.1.8.1.6.3.1.1 | Dot1agCfmMepId | not-accessible | MEPID |
| ROW dot1agCfmMaMepListRowStatus | 1.3.111.2.802.1.1.8.1.6.3.1.2 | RowStatus | read-create | The status of the row. Read SNMPv2-TC (RFC1903) for an explanation of the possible values this object can take. |
| dot1agCfmMaMepListTable | 1.3.111.2.802.1.1.8.1.6.3 | not-accessible | List of MEPIDs that belong to this MA. 12.14.6.1.3 specifies that a list of MEPIDs in all Bridges in that MA, but since SNMP SMI does not allow to state in a MIB that an object in a table is an array, the information has to be stored in another table with two indices, being the first index, the index of the table that contains the list or array. For all Bridges in which the same MAID {dot1agCfmMdFormat, dot1agCfmMdName, dot1agCfmMaNetFormat, and dot1agCfmMaNetName} is configured, the same set of dot1agCfmMaMepListIdentifiers MUST be configured in the Bridges' dot1agCfmMaMepListTables. This allows each MEP to determine whether or not it is receiving CCMs from all of the other MEPs in the MA. For example, if one were creating a new MA whose MAID were {charString, 'Dom1', charString, 'MA1'}, that had 2 MEPs, whose MEPIDs were 1 and 3, one could, in Bridge A: 1. Get a new MD index d from dot1agCfmMdTableNextIndex. 2. Create the Maintenance Domain {charString, 'Dom1'}. 3. Get a new MA index a from dot1agCfmMdMaNextIndex [d]. 4. Create the Maintenance Association {charString, 'MA1'}. 5. Create a new dot1agCfmMaMepListEntry for each of the MEPs in the MA: [d, a, 1] and [d, a, 3]. 6. Create one of the new MEPs, say [d, a, 1]. Then, in Bridge B: 7. Do all of these steps 1-6, except for using the other MEPID for the new MEP in Step 6, in this example, MEPID 3. Note that, when creating the MA, MEP List Table, and MEP entries in the second Bridge, the indices 'd' and 'a' identifying the MAID {charString, 'Dom1', charString, 'MA1'} may have different values than those in the first Bridge. | |

| dot1agCfmMaNetTable | 1.3.111.2.802.1.1.8.1.6.1 | not-accessible | The Maintenance Association table. Each row in the table represents an MA. An MA is a set of MEPs, each configured with a single service instance. This is the part of the complete MA table that is constant across all Bridges in a Maintenance Domain, and across all components of a single Bridge. That part of the MA table that can vary from Bridge component to Bridge component is contained in the dot1agCfmMaCompTable. Creation of a Service Instance establishes a connectionless association among the selected DSAPs. Configuring a Maintenance association Endpoint (MEP) at each of the DSAPs creates a Maintenance Association (MA) to monitor that connectionless connectivity. The MA is identified by a Short MA Name that is unique within the Maintenance Domain and chosen to facilitate easy identification of the Service Instance. Together, the Maintenance Domain Name and the Short MA Name form the Maintenance Association Identifier (MAID) that is carried in CFM Messages to identify incorrect connectivity among Service Instances. A small integer, the Maintenance association Endpoint Identifier (MEPID), identifies each MEP among those configured on a single MA (3.132, 18.2). This table uses two indices, first index is the index of the Maintenance Domain table. The second index is the same as the index of the dot1agCfmMaCompEntry for the same MA. The writable objects in this table need to be persistent upon reboot or restart of a device. | |

| dot1agCfmMepTable | 1.3.111.2.802.1.1.8.1.7.1 | not-accessible | The Maintenance Association Endpoint (MEP) table. Each row in the table represents a different MEP. A MEP is an actively managed CFM entity, associated with a specific DSAP of a Service Instance, which can generate and receive CFM PDUs and track any responses. It is an endpoint of a single Maintenance Association, and is an endpoint of a separate Maintenance Entity for each of the other MEPs in the same Maintenance Association (3.132). This table uses three indices. The first two indices are the indices of the Maintenance Domain and MA tables, the reason being that a MEP is always related to an MA and Maintenance Domain. The MEP table also stores all the managed objects for sending LBM and LTM. *LBM Managed objects LBM Managed objects in the MEP table enables the management entity to initiate transmission of Loopback messages. It will signal the MEP that it SHOULD transmit some number of Loopback messages and detect the detection (or lack thereof) of the corresponding Loopback messages. Steps to use entries in this table: 1) Wait for dot1agCfmMepTransmitLbmStatus value to be false. To do this do this sequence: a. an SNMP GET for both SnmpSetSerialNo and dot1agCfmMepTransmitLbmStatus objects (in same SNMP PDU). b. Check if value for dot1agCfmMepTransmitLbmStatus is false. - if not, wait x seconds, go to step a above. - if yes, save the value of SnmpSetSerialNo and go to step 2) below 2) Change dot1agCfmMepTransmitLbmStatus value from false to true to ensure no other management entity will use the service. In order to not disturb a possible other NMS do this by sending an SNMP SET for both SnmpSetSerialNo and dot1agCfmMepTransmitLbmStatus objects (in same SNMP PDU, and make sure SNmpSetSerialNo is the first varBind). For the SnmpSetSerialNo varBind, use the value that you obtained in step 1)a.. This ensures that two cooperating NMSes will not step on each others toes. Setting this MIB object does not set the corresponding LBIactive state machine variable. 3) Setup the different data to be sent (number of messages, optional TLVs,...), except do not set dot1agCfmMepTransmitLbmMessages. 4) Record the current values of dot1agCfmMepLbrIn, dot1agCfmMepLbrInOutOfOrder, and dot1agCfmMepLbrBadMsdu. 6) Set dot1agCfmMepTransmitLbmMessages to a non-zero value to initiate transmission of Loopback messages. The dot1agCfmMepTransmitLbmMessages indicates the number of LBMs to be sent and is not decremented as loopbacks are actually sent. dot1agCfmMepTransmitLbmMessages is not equivalent to the LBMsToSend state machine variable. 7) Check the value of dot1agCfmMepTransmitLbmResultOK to find out if the operation was successfully initiated or not. 8) Monitor the value of dot1agCfmMepTransmitLbmStatus. When it is reset to false, the last LBM has been transmitted. Wait an additional 5 seconds to ensure that all LBRs have been returned. 9) Compare dot1agCfmMepLbrIn, dot1agCfmMepLbrInOutOfOrder, and dot1agCfmMepLbrBadMsdu to their old values from step 4, above, to get the results of the test. *LTM Managed objects The LTM Managed objects in the MEP table are used in a manner similar to that described for LBM transmission, above. A SET operation to the variable dot1agCfmMepTransmitLtmFlags triggers the transmission of an LTM. Then, the variables dot1agCfmMepTransmitLtmSeqNumber and dot1agCfmMepTransmitLtmEgressIdentifier return the information required to recover the results of the LTM from the dot1agCfmLtrTable. | |

The low-order six octets contain a 48-bit IEEE MAC address unique to the system in which the MEP Linktrace Initiator or Linktrace Responder resides. The high-order two octets contain a value sufficient to uniquely identify the MEP Linktrace Initiator or Linktrace Responder within that system. For most Bridges, the address of any MAC attached to the Bridge will suffice for the low-order six octets, and 0 for the high-order octets. In some situations, e.g., if multiple virtual Bridges utilizing emulated LANs are implemented in a single physical system, the high-order two octets can be used to differentiate among the transmitting entities.
