Cisco Prime Network 4.2.2 Supported Technologies and Topologies
Discovery and verification techniques:
6.1.15 VLAN Service Links
A VLAN service link represents either an Ethernet or a LAG link in the context of a specific VLAN. It
connects two Ethernet Flow Point entities, which represent Ethernet or LAG ports in the context of a
specific VLAN, or with VLAN match criteria.
connects two Ethernet Flow Point entities, which represent Ethernet or LAG ports in the context of a
specific VLAN, or with VLAN match criteria.
The two Ethernet Flow Points can reside in the same Layer 2 domain, or connect between two different
Layer 2 domains when a VLAN TAG manipulation is used.
Layer 2 domains when a VLAN TAG manipulation is used.
The VLAN service links are not discovered using the standard topology mechanism that resides in the
VNE layer, but rather by the Carrier Ethernet discovery. The discovery mechanism uses Ethernet and
LAG links, VNE inventory modeling information of the Ethernet/LAG interfaces, and Ethernet Flow Point
entities as inputs for the VLAN service link discovery process.

6.1.16 MPLS-TE Tunnel
The MPLS-TE Tunnel topology represents a unidirectional link between the TE tunnel interface, which is
the head of the TE tunnel, and the Label Switching Entity (LSE), which is the tail of the TE tunnel. The
head of the TE tunnel is represented by the MPLS-TE Tunnel IMO (IMplsTETunnel) and the tail of the TE
tunnel is represented by the Label Switching Entity IMO (ILSE), which is the MPLS forwarding component
on the destination VNE.

head of the TE tunnel is represented by the MPLS-TE Tunnel IMO (IMplsTETunnel) and the tail of the TE
tunnel is represented by the Label Switching Entity IMO (ILSE), which is the MPLS forwarding component
on the destination VNE.
MPLS TE tunnels also have mid-points that are not represented in the MPLS-TE tunnel topology.
Link type: MPLS-TE, P2MP MPLS-TE
The link is unidirectional and represents a flow from the head to the tail of the TE tunnel.
The link is unidirectional and represents a flow from the head to the tail of the TE tunnel.
Link type ‘MPLS-TE’ will be used when TE tunnel has a single LSP (i.e. for point to point) and ‘P2MP
MPLS-TE’ will be used for TE tunnel with multiple LSPs (i.e. for point to multi point).
