IEEE8021-CFM-MIB
About this MIB
Connectivity Fault Management (CFM) is the name of the feature defined in IEEE 802.1ag for end-to-end Operations, Administration and Maintenance (OAM) for Ethernet. In the Comware platform, the feature is called Connectivity Fault Detection (CFD).
CFD is an end-to-end per-VLAN link layer OAM mechanism. CFD is used for link connectivity detection, fault verification, and fault location.
This MIB defines how to implement CFD. Use this MIB to configure CFD on managed devices.

Notification triggers
This notification is sent when the MEP continuously fails.
Possible causes might include the following:
The CFD entities at the two ends have inconsistent MDs or MAs.
The CFD entities at the two ends have inconsistent CCM intervals.
The MEP ID in CCMs is not in the MEP ID on the local end.
No CCM is received upon expiration of the specified timer.
System impact
Continuity check cannot be performed. Service traffic switchover or interruption might occur.
Status control
This notification cannot be disabled.

Recommended action
To resolve this issue:
1.Identify whether the CFD configuration is correct.
2.Identify whether the port and link states are normal.
3.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.
