CISCO-ETHER-CFM-MIB

        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.

These commands use the standard Observium installation path and load the selected MIB variant before the RFC and Net-SNMP directories.

cEtherCfmCcMepDown cEtherCfmEventServiceId cEtherCfmEventLclMacAddress cEtherCfmEventLclMepCount cEtherCfmEventLclIfCount cEtherCfmEventRmtMepid cEtherCfmEventRmtMacAddress cEtherCfmEventCode	`.1.3.6.1.4.1.9.9.461.0.0.2`	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.
cEtherCfmCcCrossconnect cEtherCfmEventServiceId cEtherCfmEventLclMacAddress cEtherCfmEventRmtMepid cEtherCfmEventRmtMacAddress cEtherCfmEventRmtServiceId	`.1.3.6.1.4.1.9.9.461.0.0.3`	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.
cEtherCfmCcLoop cEtherCfmEventServiceId cEtherCfmEventLclMacAddress cEtherCfmEventLclMepid	`.1.3.6.1.4.1.9.9.461.0.0.4`	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.
cEtherCfmCcConfigError cEtherCfmEventServiceId cEtherCfmEventLclMacAddress cEtherCfmEventLclMepid cEtherCfmEventRmtMacAddress	`.1.3.6.1.4.1.9.9.461.0.0.5`	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.
cEtherCfmXCheckMissing cEtherCfmEventServiceId cEtherCfmEventLclMacAddress cEtherCfmEventRmtMepid cEtherCfmEventRmtMacAddress	`.1.3.6.1.4.1.9.9.461.0.0.6`	This notification is generated when an expected (configured) MEP does not come up during the cross-check start timeout interval.
cEtherCfmXCheckUnknown cEtherCfmEventServiceId cEtherCfmEventLclMacAddress cEtherCfmEventRmtMepid cEtherCfmEventRmtMacAddress	`.1.3.6.1.4.1.9.9.461.0.0.7`	This notification is generated when an unexpected MEP comes up.
cEtherCfmXCheckServiceUp cEtherCfmEventServiceId cEtherCfmEventLclMacAddress	`.1.3.6.1.4.1.9.9.461.0.0.8`	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.
