Use Case Description  
The EMS must validate the data provided by the NMS and disassociate the requested MFDs 
from the specified FD. If the EMS cannot disassociate the specified MFDs, an appropriate 
exception is raised. Best effort is not supported. The operation also disassociates the fdEdge 
CPTPs that are associated to the MFDs to be disassociated. After the disassociation, the EMS 
verifies the server layer connectivity between the associated MFDs using the FD Connectivity 
State attribute. 
The following describes how the system requests to disassociate MFDs from an existing FD: 
1.  The NMS sends the request to the EMS to disassociate MFDs from an existing FD. 
2.  The EMS validates the request: 
a.  If the syntax is incorrect, an Invalid Input exception is raised. 
b.  If the specified FD is unknown to the EMS, an Entity Not Found exception is raised. 
c.  If one or more of the specified MFDs were not previously associated to the FD, an Unable To 
Comply exception is raised. 
d.  If one or more of the specified MFDs is carrying traffic, an Object In Use exception is raised. 
e.  If any fdEdge CPTPs cannot be disassociated from the MFDs that are being disassociated (the 
PortTPRoleState attribute of the CPTPs is set to assigned), no fdEdge CPTPs are disassociated 
and an Unable To Comply exception is raised. 
f.  If any of the MFDs could not be disassociated, no MFD is disassociated and an Unable To 
Comply exception is raised. 
3.  If the request is valid, the EMS: 
a.  Disassociates the specified MFDs from the FD. 
b.  Replies with a success indication. 
c.  Sends an attribute value change notification to the notification service using the 
MatrixFlowDomain attribute of the FD. The notification includes the complete list of MFD 
names that are associated to the FD. 
d.  Verifies the server layer connectivity between the associated MFDs. The FD Connectivity State 
attribute is modified accordingly (fully connected, not fully connected, or unknown). 
4.  If the FD Connectivity State attribute is modified, the EMS sends a state change notification to the 
notification service. 
5.  If the request is successful: 
a.  The requested MFDs are disassociated from the FD. 
b.  The corresponding fdEdge CPTPs are also disassociated from the FD. 
c.  If the request fails, there is no change in the system or the MFD association to the FD. 
Limitations 
Notification changes are not sent.
