Description
This MIB module defines the managed objects and notifications for Ethernet Connectivity Fault Management (CFM). CFM is an end-to-end per service instance Ethernet layer Operations, Administration and Management (OAM) protocol. CFM events include: - Maintenance End-Point (MEP) coming up: establishing connectivity - Maintenance End-Point going down: losing connectivity - Maintenance End-Point unknown: unexpected - Maintenance End-Point missing: expected but not reachable - Continuity Check Configuration Error: collision in MEP IDs - Continuity Check Loop: forwarding loop in network - Continuity Check Cross-connect: cross-connected forwarding path. The following acronyms are used in this module: - MEP: Maintenance End Point - MEPID: Maintenance End Point Identifier - CC: Continuity Check - CCDB: Continuity Check Database - SVLAN: Service Provider Virtual Local Area Network - VLAN: Virtual Local Area Network - CLI: Command Line Interface. - OAM: Operations Administration and Management.

| cEtherCfmMaxEventIndex OBJECT-TYPE This object specifies the maximum upper value supported for the cEtherCfmEventIndex index by this agent. | 1.3.6.1.4.1.9.9.461.1.1.1 | Unsigned32 (1..4294967295) | read-only | current |
| cEtherCfmEventTable OBJECT-TYPE This table contains a collection of Ethernet CFM notifications generated by the device. The notifications correspond to events recognized by the device and fall into the following classes: - MEP-Up - MEP-Down - Configuration Error - Forwarding Loop - Cross-connected Ethernet Connection - Crosscheck Missing MEP - Crosscheck Unknown MEP - Crosscheck Service Up A conceptual row is created in this table whenever the device encounters one of the events listed above. Rows can only be created by the agent, and not at the request of the management station. Rows are deleted at the request of a management station by setting the cEtherCfmEventDeleteRow object to 'delete'. Another way of deleting rows is through the CLI. Although this table may be indexed uniquely by the cEtherCfmEventIndex index, the first two indices (cEtherCfmEventDomainIndex and cEtherCfmEventSvlan) are used to speed-up queries per maintenance domain and per customer service instance. Furthermore, these two indices will help in defining the MIB views easily in order to restrict access to the MIB to particular entities (be it a service provider, or operator, or customer). | 1.3.6.1.4.1.9.9.461.1.1.2 | not-accessible | current | |
| cEtherCfmEventEntry OBJECT-TYPE An entry in this table is created for every event reported by Ethernet CFM. | 1.3.6.1.4.1.9.9.461.1.1.2.1 | not-accessible | current | |
| cEtherCfmEventDomainIndex OBJECT-TYPE This object represents the ID which uniquely identifies a CFM maintenance domain on the device.

| cEtherCfmEventRmtPortState OBJECT-TYPE The operational state of the port on which the remote MEP is configured. This information is derived from the port-state as indicated in the CC message. The possible values are: 'up' - The port is operationally up. 'down' - The port is operationally (but not administratively) down. 'adminDown' - The port is administratively down. 'test' - The port is in test mode (perhaps due to an IEEE Standard 802.3ah OAM intrusive loopback operation). 'remoteExcessiveErrors' - 802.3ah OAM reports that the other end of the link is receiving an excessive number of invalid frames. 'localExcessiveErrors' - 802.3ah OAM reports that this end of the link is receiving an excessive number of invalid frames. 'localNoData' - No data and no CFM messages have been received for an excessive length of time. | 1.3.6.1.4.1.9.9.461.1.1.2.1.14 | INTEGER {up(1), down(2), adminDown(3), test(4), remoteExcessiveErrors(5), localExcessiveErrors(6), localNoData(7)} | read-only | current |

| cEtherCfmEventCode OBJECT-TYPE This object is used in decoding 'mepUp' and 'mepDown' events. ** For 'mepUp', the following codes are relevant: 'new' - This is the very first time the device receives a CC message from the remote MEP. 'returning' - The device received a CC message from a remote MEP for which it had an expired CCDB entry. 'portState' - The device received a CC message from a remote MEP for which it has a valid CCDB entry, and the message indicates a port status change. ** For 'mepDown', the following codes are relevant: 'lastGasp' - The device received a CC message from a remote MEP with zero lifetime. 'timeout' - The local CCDB entry for the remote MEP expired. 'configClear' - A previous CC message from a MEP that triggered a configuration error event is cleared. 'loopClear' - A previous CC message from a MEP that triggered a loop error event is cleared. 'xconnectClear' - A previous CC message from a MEP that triggered a crossconnect error event is cleared. 'unknownClear' - A previous CC message from a MEP that triggered an unknown MEP event is cleared. | 1.3.6.1.4.1.9.9.461.1.1.2.1.16 | INTEGER {new(1), returning(2), portState(3), lastGasp(4), timeout(5), configClear(6), loopClear(7), xconnectClear(8), unknownClear(9)} | read-only | current |
| cEtherCfmEventDeleteRow OBJECT-TYPE This object allows the management station to delete a row in the cEtherCfmEventTable in order to free system resources. When reading this object the value of 'noop' will be returned. This object can only be set to 'delete'. When this object is set to 'delete', the conceptual row corresponding to this object will be deleted to free system resources. This is equivalent to clearing the event log. Should the trigger that caused the event to be logged reoccur, the event will be re-asserted but in a different conceptual row. | 1.3.6.1.4.1.9.9.461.1.1.2.1.17 | INTEGER {noop(1), delete(2)} | read-write | current |

Notifications
| Name | OID | Status |
|---|---|---|
| cEtherCfmCcMepUp NOTIFICATION-TYPE This notification is generated in the following cases: - when a remote MEP first comes up, that is when we receive a CC message from that MEP for the first time. - when the device receives a CC message from a MEP for which it has an expired CCDB entry. - when a CC message is received for a remote MEP for which the device already has a CCDB entry and the port-state in the received CC message is different from the cached previous state. | 1.3.6.1.4.1.9.9.461.0.0.1 | current |
| cEtherCfmCcMepDown NOTIFICATION-TYPE This notification is generated when a remote MEP goes down; i.e. the entry in CCDB corresponding to this MEP times out or the device receives a CC message with zero hold-time. | 1.3.6.1.4.1.9.9.461.0.0.2 | current |
| cEtherCfmCcCrossconnect NOTIFICATION-TYPE This notification is generated when a device receives a CC message with the service ID not matching the one locally configured for the VLAN in question. | 1.3.6.1.4.1.9.9.461.0.0.3 | current |
| cEtherCfmCcLoop NOTIFICATION-TYPE This notification is generated when a device receives a CC message with the same MEPID and MAC address as those of the device itself, indicating that there is a forwarding loop and that the device is receiving its own CC messages. | 1.3.6.1.4.1.9.9.461.0.0.4 | current |
| cEtherCfmCcConfigError NOTIFICATION-TYPE This notification is generated when a device receives a CC message with the same MEPID but different MAC address as those of the device itself, indicating that there is a mis-configuration in the network where a remote device has the same MEPID configured. | 1.3.6.1.4.1.9.9.461.0.0.5 | current |
| cEtherCfmXCheckMissing NOTIFICATION-TYPE This notification is generated when an expected (configured) MEP does not come up during the cross-check start timeout interval. | 1.3.6.1.4.1.9.9.461.0.0.6 | current |
| cEtherCfmXCheckUnknown NOTIFICATION-TYPE This notification is generated when an unexpected MEP comes up. | 1.3.6.1.4.1.9.9.461.0.0.7 | current |
| cEtherCfmXCheckServiceUp NOTIFICATION-TYPE This notification is generated when all the MEPs belonging to a customer service instance come up before the expiration of the cross-check start timeout interval. | 1.3.6.1.4.1.9.9.461.0.0.8 | current |
