Download standard MIB format if you are planning to load a MIB file into some system (OS, Zabbix, PRTG ...) or view it with a MIB browser. CSV is more suitable for analyzing and viewing OID' and other MIB objects in excel. JSON and YAML formats are usually used in programing even though some systems can use MIB in YAML format (like Logstash).
Keep in mind that standard MIB files can be successfully loaded by systems and programs only if all the required MIB's from the "Imports" section are already loaded.
The tree-like SNMP object navigator requires no explanations because it is very simple to use. And if you stumbled on this MIB from Google note that you can always go back to the home page if you need to perform another MIB or OID lookup.

 ieee8021cfmMIB 1.3.111.2.802.1.1.8
Connectivity Fault Management module for managing IEEE 802.1ag
     dot1agNotifications 1.3.111.2.802.1.1.8.0
         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 table entry (dot1agCfmMaTable). dot1agCfmMepIdentifier - MEP Identifier and final index into the MEP table (dot1agCfmMepTable).

             dot1agCfmDefaultMdTable 1.3.111.2.802.1.1.8.1.2.4 no-access
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 subclause 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 subclause 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.

             dot1agCfmMdTable 1.3.111.2.802.1.1.8.1.5.2 no-access
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 1.3.111.2.802.1.1.8.1.5.2.1 no-access
The Maintenance Domain table entry. This entry is not lost upon reboot. It is backed up by stable storage.

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.
                     dot1agCfmMdFormat 1.3.111.2.802.1.1.8.1.5.2.1.2 dot1agcfmmaintdomainnametype read-only

             dot1agCfmMaTable 1.3.111.2.802.1.1.8.1.6.1 no-access
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.

             dot1agCfmMepTable 1.3.111.2.802.1.1.8.1.7.1 no-access
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.
