Description: State of this Default MD Level table entry. True if there is no entry in the Maintenance Association table defining an MA for the same VLAN ID and MD Level as this table's entry, and on which MA an Up MEP is defined, else false. **NOTE: this object is deprecated due to re-indexing of the table.
What is dot1agCfmDefaultMdStatus?
This boolean status object indicates whether a default Connectivity Fault Management (CFM) Maintenance Domain entry is active or has been overridden by a more specific Maintenance Association (MA) defined in the same VLAN and maintenance level. The CFM default MD is automatically created for all VLANs but becomes logically disabled when an explicit MA is configured for that VLAN/level combination. A network operator examines this status to understand the CFM topology and verify that intended MA hierarchies are in place for Ethernet OAM (Operations, Administration, and Maintenance) monitoring.
