Description: Manages ZTE ZXR10 router Ethernet CFM maintenance domains, MEPs, and connectivity fault operations.
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 ZXR10-CFM-MIB?
ZXR10-CFM-MIB implements IEEE 802.1ag Connectivity Fault Management on ZTE's ZXR10 router/switch family, managing Ethernet OAM maintenance domains, maintenance associations, and maintenance endpoints (MEPs) used for continuity-check, loopback, and linktrace operations. It exposes fault-management configuration (domain/association definitions, MEP state) and CFM fault notifications. It is directly used to monitor Ethernet service-level connectivity health -- detecting link failures, misconnectivity, or unexpected remote-MAC conditions across a carrier Ethernet path -- rather than general device hardware status. It directly implements the IEEE 802.1ag standard and overlaps conceptually with the IETF's dot1agCfmMib. It is typically deployed on ZXR10 switches/routers delivering carrier Ethernet services where end-to-end fault detection across a metro or WAN Ethernet path is required. Engineers can download the ZXR10-CFM-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ZXR10-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
- ZTE ZXR10 switch/router (carrier Ethernet)
Monitoring Examples
No specific object names were present in the source, so the following scenario is inferred from module_desc: an operator would check the remote-MEP database within a maintenance association to confirm continuity-check messages are being received from the far-end MEP. A missing remote-MEP entry, or a CFM fault notification firing, would indicate a break in the Ethernet service path between the two endpoints even while the physical link itself appears up.
What Can Be Monitored
- maintenance domain/association configuration
- MEP operational status
- remote MEP continuity state
- CFM fault notifications

How to Use in IPNetwork Monitor
Example using dot1agCfmMepCciSentCcms OID:
Select a ZTE ZXR10 switch/router, carrier Ethernet (802.1ag MEP continuity-check/fault-notification 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 dot1agCfmMepCciSentCcms 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. It reports the total number of Continuity Check messages 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.
OIDs

|---|---|---|---|---|
| zxr10cfmMIB | 1.3.6.1.4.1.3902.3.120 | Connectivity Fault Management module for managing IEEE 802.1ag | ||
| dot1agNotifications | 1.3.6.1.4.1.3902.3.120.0 | |||
| NTF dot1agCfmFaultAlarm | 1.3.6.1.4.1.3902.3.120.0.1 | 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 table entry (dot1agCfmMaTable). dot1agCfmSessionId - MEP Identifier and final index into the MEP table (dot1agCfmMepTable). | ||

| NUM dot1agCfmMdTableNextIndex | 1.3.6.1.4.1.3902.3.120.1.1.1 | Dot1afCfmIndexIntegerNextFree | read-only | This object contains an unused value for dot1agCfmMdIndex in the dot1agCfmMdTable, or a zero to indicate that none exist. |
| dot1agCfmMdTable | 1.3.6.1.4.1.3902.3.120.1.1.2 | not-accessible | The Maintenance Domain table. Each row in the table represents a different Maintenance Domain. A Maintenance Domain is described in 802.1ag (3.22) as the network or the part of the network for which faults in connectivity are to be managed. The boundary of a Maintenance Domain is defined by a set of DSAPs, each of which can become a point of connectivity to a service instance. | |
| dot1agCfmMdEntry | 1.3.6.1.4.1.3902.3.120.1.1.2.1 | not-accessible | The Maintenance Domain table entry. This entry is not lost upon reboot. It is backed up by stable storage. | |
| U32 dot1agCfmMdIndex | 1.3.6.1.4.1.3902.3.120.1.1.2.1.1 | Unsigned32 | not-accessible | The index to the Maintenance Domain table. dot1agCfmMdTableNextIndex needs to be inspected to find an available index for row-creation. Referential integrity is required i.e. the index needs to be persistent upon a reboot or restart of a device. The index can never be reused for other Maintenance Domain. The index value should keep increasing up to the time that they wrap around. This is to facilitate access control based on OID. |
| NUM dot1agCfmMdFormat | 1.3.6.1.4.1.3902.3.120.1.1.2.1.2 | Dot1agCfmMaintDomainNameType | read-only | The type (and thereby format) of the Maintenance Domain Name. |
| NUM dot1agCfmMdName | 1.3.6.1.4.1.3902.3.120.1.1.2.1.3 | Dot1agCfmMaintDomainName | read-only | The Maintenance Domain name. The type/format of this object is determined by the value of the dot1agCfmMdNameType object. Each Maintenance Domain has unique name amongst all those used or available to a service provider or operator. It facilitates easy identification of administrative responsibility for each Maintenance Domain. Clause 3.24 defines a Maintenance Domain name as the identifier, unique over the domain for which CFM is to protect against accidental concatenation of Service Instances, of a particular Maintenance Domain. |
| DOT dot1agCfmMdMdLevel | 1.3.6.1.4.1.3902.3.120.1.1.2.1.4 | Dot1agCfmMDLevel | read-only | The Maintenance Domain Level. |

| DOT dot1agCfmMdMhfIdPermission | 1.3.6.1.4.1.3902.3.120.1.1.2.1.6 | Dot1agCfmIdPermission | read-only | Enumerated value indicating what, if anything, is to be included in the Sender ID TLV (21.5.3) transmitted by MPs configured in this Maintenance Domain. Since, in this variable, there is no encompassing Maintenance Domain, the value sendIdDefer takes the meaning of sendIdChassisManage. |
| NUM dot1agCfmMdMaTableNextIndex | 1.3.6.1.4.1.3902.3.120.1.1.2.1.7 | Dot1afCfmIndexIntegerNextFree | read-only | Value to be used as the index of the MA table entries for this Maintenance Domain when the management entity wants to create a new row in the MA table. |
| ROW dot1agCfmMdRowStatus | 1.3.6.1.4.1.3902.3.120.1.1.2.1.8 | RowStatus | read-only | The status of the row. The writable columns in a row can not be changed if the row is active. All columns must have a valid value before a row can be activated. |

| dot1agCfmMaTable | 1.3.6.1.4.1.3902.3.120.1.2.1 | 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. Creation of a Service Instance establishes a connectionless association among the selected DSAPs. Configuring a Maintenance association End Point (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 End Point Identifier (MEPID), identifies each MEP among those configured on a single MA (802.1ag clauses 3.17 and 18.2). This table uses two indices, first index is the index of the Maintenance Domain table. The writable objects in this table need to be persistent upon reboot or restart of a device. | |
| dot1agCfmMaEntry | 1.3.6.1.4.1.3902.3.120.1.2.1.1 | not-accessible | The MA table entry. | |

| dot1agCfmMaMepListTable | 1.3.6.1.4.1.3902.3.120.1.2.3 | not-accessible | List of MEPIDs (in any bridge) that belong to the same MA. Clause 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. | |

| dot1agCfmMepTable | 1.3.6.1.4.1.3902.3.120.1.3.1 | not-accessible | The Maintenance Association End Point (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 end point 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 (802.1ag clause 3.18). 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 Transmit Loopback table. Entries in this table are created/removed at the same time than entries in the MEP table are created/removed. 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 'ready'. 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 'ready' - 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 'ready' to 'notReady' 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. 3) Setup the different data to be sent (number of messages, optional TLVs,...). 4) Record the current values of dot1agCfmMepLbrIn, dot1agCfmMepLbrInOutOfOrder, and dot1agCfmMepLbrBadMsdu. 6) Change dot1agCfmMepTransmitLbmStatus value from 'notReady' to 'transmit' to initiate transmission of Loopback messages. 7) Check the value of dot1agCfmMepTransmitLbmResultOK to find out if the operation was successfully initiated or not. 8) Monitor the value of dot1agCfmMepTransmitLbmMessages. When it reaches 0, 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. 10) Change the dot1agCfmMepTransmitLbmStatus value back to 'ready' to allow other management entities to use the table. *LTM Managed objects The LTM Managed objects in the MEP table are used in a manner similar to that described for LBM transmission, above. Upon successfully initiating the transmission, the variables dot1agCfmMepTransmitLtmSeqNumber and dot1agCfmMepTransmitLtmEgressIdentifier return the information required to recover the results of the LTM from the dot1agCfmLtrTable. | |

| DOT dot1agCfmSessionId | 1.3.6.1.4.1.3902.3.120.1.3.1.1.1 | Dot1agCfmSessionId | not-accessible | Integer that is unique among all the MEPs in the same MA. Other definition is: a small integer, unique over a given Maintenance Association, identifying a specific Maintenance association End Point (3.19). MEP Identifier is also known as the MEPID. |
| NUM dot1agCfmMepIfIndex | 1.3.6.1.4.1.3902.3.120.1.3.1.1.2 | InterfaceIndexOrZero | read-only | This object is the interface index of the interface either a bridge port, or an aggregated IEEE 802.1 link within a bridge port, to which the MEP is attached. Upon a restart of the system, the system SHALL, if necessary, change the value of this variable so that it indexes the entry in the interface table with the same value of ifAlias that it indexed before the system restart. If no such entry exists, then the system SHALL set this variable to 0. |

| T/F dot1agCfmLtrForwarded | 1.3.6.1.4.1.3902.3.120.1.3.2.1.4 | TruthValue | read-only | Indicates if a LTM was forwarded by the responding MP, as returned in the 'FwdYes' flag of the flags field. |
| T/F dot1agCfmLtrTerminalMep | 1.3.6.1.4.1.3902.3.120.1.3.2.1.5 | TruthValue | read-only | A boolean value stating whether the forwarded LTM reached a MEP enclosing its MA, as returned in the Terminal MEP flag of the Flags field. |
| OCT dot1agCfmLtrLastEgressIdentifier | 1.3.6.1.4.1.3902.3.120.1.3.2.1.6 | OCTET STRING | read-only | An octet field holding the Last Egress Identifier returned in the LTR Egress Identifier TLV of the LTR. The Last Egress Identifier identifies the MEP Linktrace Initiator that originated, or the Linktrace Responder that forwarded, the LTM to which this LTR is the response. This is the same value as the Egress Identifier TLV of that LTM. |
| OCT dot1agCfmLtrNextEgressIdentifier | 1.3.6.1.4.1.3902.3.120.1.3.2.1.7 | OCTET STRING | read-only | An octet field holding the Next Egress Identifier returned in the LTR Egress Identifier TLV of the LTR. The Next Egress Identifier Identifies the Linktrace Responder that transmitted this LTR, and can forward the LTM to the next hop. This is the same value as the Egress Identifier TLV of the forwarded LTM, if any. If the FwdYes bit of the Flags field is false, the contents of this field are undefined, i.e. any value can be transmitted, and the field is ignored by the receiver. |

| dot1agCfmMepDbTable | 1.3.6.1.4.1.3902.3.120.1.3.3 | not-accessible | The MEP Database. A database, maintained by every MEP, that maintains received information about other MEPs in the Maintenance Domain. The SMI does not allow to state in a MIB that an object in a table is an array. The solution is to take the index (or indices) of the first table and add one or more indices. | |
