Viewing MPLS Logical Inventory
The following topics describe the device logical inventory specific to MPLS VPNs including routing
entities, LSEs, BGP neighbors, Multiprotocol BGP (MP-BGP), VRF instances, and pseudowire and TE
tunnels. Topics include:
• MPLS VPN Logical Inventory Overview, page 5-1—Introduces the concepts of physical and logical
inventory.
• Viewing MPLS VPN Properties, page 5-2—Describes MPLS VPN logical inventory properties
viewed from the inventory window including routing entities, label switched entities, MP-BGP
properties, and VRF properties.
• Viewing Port Configuration, page 5-11—Describes port configuration information.
• Viewing Pseudowire End-to End Emulation Tunnels, page 5-12—Describes the Layer 2 pseudowire
tunnel properties.
• Viewing MPLS TE Tunnel Information, page 5-13—Describes the TE tunnel properties.
• Viewing Access List Information, page 5-14—Describes access list item properties.
Note For a general description of logical inventory and the inventory window, see the Cisco Active Network
Abstraction 3.6.6 User Guide.
MPLS VPN Logical Inventory Overview
Every NE managed by Cisco ANA is assigned to an autonomous virtual network element (VNE). The
VNE continuously investigates the NE status and configuration so that Cisco ANA can display an
accurate virtual model of both the NE and the network in which the NE resides.
VNEs continuously update an NE’s physical and logical inventory. You can view an NE’s physical and
logical inventory in the Cisco ANA device inventory window. The physical inventory contains all the NE
physical components (and their properties) such as chassis, shelves, cards, and ports. The VNE detects
status changes or the addition or removal of components (such as a card) and reflects the changes in the
physical inventory.
Cisco ANA VNEs also investigate the logical inventory of each device. The logical inventory reflects
dynamic data such as configurations, forwarding, and service-related components including traffic
profiles. The logical inventory also displays virtual circuits, cross-connect tables, routing, bridging, and
LSE tables, and other logical elements. Cisco ANA NetworkVision displays the physical and logical
inventory and allows you to drill down to detailed physical and logical inventory views.
