4.6.1.4.3 Exceptions
internalError: Indicates that an internal error or exception has occurred as part of this call.
invalidInput: Indicates that the input given to the operation is invalid.
NOTE:
1. This API provides the internal patch chords that are part of the NCS2K participating in an OCHTrail UNI
setup. The internal patch chords will be grouped for a given network element.
2. The response to an OCH Trail UNI will contain the LMP links between the NCS2K and NCS4K nodes in
addition to the physical links between the NCS2K nodes.
3. The Internal patch chords of an NCS2K will be listed as Topological Links. The Vendor extension part of
the Topological Links will contain the “orderNumber” to indicate the patch chord order. There will be
even number of patch chords in each device. First half of the patch chords will represent the forward
direction, the second half will represent the reverse direction.
4.7 FlowDomainRetrieval (Carrier Ethernet Inventory)
An EVC Flow Domain Fragment (FDFr) is a logical entity that contains a transparent end-to-end connectivity
between two or more FPs (at the same connectionless layer) within an FD. The FDFr represents a Virtual
Private Network (VPN) for a single customer in the provider network and enables the flow of traffic between
FPs.
The server-layer CPTPs of the FPs that are connected through an FDFr must be assigned to MFDs that are
associated to the FD that contains the FDFr. If traffic arrives at a point that is a member of an FDFr, it
emerges at one or more of the other edge FPs that are members of the same FDFr.
The edge FPs that act as endpoints of the FDFr can be associated with CPTPs connected to customer domains
or to other provider domains (of the same or different providers). The VLAN IDs of the FPs of the same FDFr
must be equal and in particular must be the VLAN ID of the outermost frame. An FDFr may also support
untagged frames or may be unaware of frame tags.
4.7.1 Flow Domain Fragment Data

List of RDN types representing an FDFr. Consists
of MD, FDFR.
