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). |

'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.

received for an excessive length of
time. |

1.3.6.1.4.1.9.9.461.1.1.2.1.16 |
| 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. |

- 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. |
