ciscoEtherCfmMIB 1.3.6.1.4.1.9.9.461
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.

cEtherCfmEventTable 1.3.6.1.4.1.9.9.461.1.1.2
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).

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.

cEtherCfmEventDeleteRow 1.3.6.1.4.1.9.9.461.1.1.2.1.17
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.
