MPLS TE Tunnel Interface
The following Network/Data Link layer MPLS TE Tunnel Interface object, is bound by its Containing Termination Points attribute to a Data Link Layer Interface object, and is primarily being accessed by Network layer IP Interface bound by its Contained Connection Termination Points attribute. It is also being accessed by Label Switching Entity.

MPLS TE Tunnel Segment
The following MPLS TE Tunnel Segment object describes, as the name implies, the properties of a single segment of an MPLS TE Tunnel, which is being used by the Graphical User Interface [GUI] of the management application for visualizing the MPLS TE Tunnels network and has no effect on the Virtual Network Element [VNE] logic implementation. The segments are aggregated in MPLS TE Tunnel Segments table of the Label Switching Entity.

Network Topology
The discovery of Multi Protocol Label Switching Traffic Engineering [MPLS-TE] Network layer topology is unsupported.
Service Alarms
The following alarms are supported for this technology:
•
MPLS TE Tunnel Down/MPLS TE Tunnel Up
•
MPLS TE Tunnel Flapping/MPLS TE Tunnel Up or Down
These alarms are disabled by default.
Note
For a detailed description of these alarms and for information about correlation see the Cisco Active Network Abstraction MPLS User Guide, 3.6.
