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.

·     The dot1agCfmMdIndex index must be configured. The index is provided by the dot1agCfmMdTableNextIndex object.

·     The dot1agCfmMdMdLevel object must be configured.

·     The dot1agCfmMdFormat object is optional. If it is not configured, the default value is charString(4).

·     The dot1agCfmMdName object is optional. When the dot1agCfmMdFormat object is set to none(1), the MIB will automatically ignore the input value no matter whether the dot1agCfmMdName object is configured. When the dot1agCfmMdFormat object is set to any other value, you must configure the dot1agCfmMdName object, and the MIB will read the input value.

·     The dot1agCfmMdMhfCreation object is optional. If it is not configured, the default value is defMHFnone(1), and only the value is available.

·     The dot1agCfmMdMhfIdPermission object is optional. If it is not configured, the default value is sendIdNone(1), and only the value is available.
