This attribute specifies the data path to be used by Virtual Circuits
on this interface. The value of the dataPath attribute in the Dna
component is overridden by this attribute if the value is not
useDnaValue.
This value applies to the connection after data transfer state is
reached. All the data and control traffic will be sent using this data
path. If the provisioned dataPath is not available the connection is
not established.
The value of the dataPath is signalled by both ends of the
connection. If this value is not the same at both ends dprsOnly is
used for the duration of the connection.
A virtual circuit connection is always established using dprsOnly
even if this attribute is provisioned as some other value.
dprsOnly - The dynamic packet routing system is used.
dprsMcsOnly - The DPRS Multi-Service Cut-Through Switching
path is used.
dprsMcsFirst - The DPRS Multi-Service Cut-Through Switching
path is used if it is available. If it is not available, dprsOnly is used.
useDnaValue - The routing system used is based on the value
provisioned in the Dna component.
