The following table shows the relationships between the variables that indicate defects, the
priorities of these defects, and the enumerated value reported in the Fault Alarm for each defect.
The
highestDefectPri
is an integer value indicating the priority of the defect named in the variable
highestDefect.
The
highestDefect
variable is readable as a managed object. It is an enumerated value indicating
the highest priority defect.

Argument Description
priority
Specifies the defect priority for the specified MEP, in the range <0-5>.
1-8191
Specifies the MEP ID of the MEP, in the specified range.
Example
In this example if the defect priority of the MEP ID 10 is set to 3, the MEP will report about all
defects conditions occurred with priority equal and higher than 3. It will announce the lack of
CCMs from some other MEPs in its configured list and will ignore the MAC status defects and the
reception of valid CCMs with RDI bit set.

Updating the Remote MEPs List
The
clear connectivity
command, in Specific Maintenance Association mode, clears the remote
MEPs list connectivity. If the
clear connectivity
command is applied, all corresponding down
remote MEPs are eliminated. If
clear connectivity
MEPID
is applied, only the specified MEPID is
eliminated.
The data of the remote MEPs that did not send CCMs for a period of time and are in DOWN states
will be removed. The active MEPs over the Maintenance Association will be restored in the CFM
connectivity table. Their counters will be reset.
