Abstract
A network element configured to support Connectivity Fault Management (CFM) for Operation, Administration and Maintenance (OAM) includes circuitry configured to track faults in the CFM via a defect indication variable that includes multiple bits wherein each bit is one of a certain priority level of a plurality of priority levels and a reserved value, and, responsive to one or more of detection of a new fault and clearing of an existing fault, update the defect indication variable accordingly based on a corresponding priority level of the new fault or the existing fault.

A network element configured to support Connectivity Fault Management (CFM) for Operation, Administration and Maintenance (OAM) comprising circuitry configured to:
- track faults in the CFM via a defect indication variable that includes multiple bits wherein each bit represents one or more of a certain priority level of a plurality of priority levels and a reserved value, and
- responsive to one or more of detection of a new fault and clearing of an existing fault, update the defect indication variable accordingly based on a corresponding priority level of the new fault or the existing fault.
A non-transitory computer-readable medium configured to store computer logic having instructions that, when executed, cause a network element to:
- track faults in the Connectivity Fault Management (CFM) via a defect indication variable that includes multiple bits wherein each bit represents one or more of a certain priority level of a plurality of priority levels and a reserved value, and
- responsive to one or more of detection of a new fault and clearing of an existing fault, update the defect indication variable accordingly based on a corresponding priority level of the new fault or the existing fault.
A method comprising steps of:
- tracking faults in the Connectivity Fault Management (CFM) via a defect indication variable that includes multiple bits wherein each bit represents one or more of a certain priority level of a plurality of priority levels and a reserved value, and
- responsive to one or more of detection of a new fault and clearing of an existing fault, updating the defect indication variable accordingly based on a corresponding priority level of the new fault or the existing fault.
