UsageRestriction

Data type: uint16
Access type: Read-only

In some circumstances, a logical port might be identifiable as a front end or back end port. An example of this situation would be a storage array that might have back end ports to communicate with disk drives and front end ports to communicate with hosts. If there is no restriction on the use of the port, then the value should be set to 4 (Not Restricted). This property is inherited from CIM_LogicalPort and it is set to 4 (Not Restricted).
