Cisco Prime Network 4.2.2 Supported Technologies and Topologies
Note: Many service providers use L2PT to configure customer access to VLAN ports. This avoids
the need to process Layer 2 protocols such as CDP. In these scenarios, discovery may
create links between ports that are not directly connected, because the Layer 2 protocol
information is tunneled and does not reflect the actual physical links. This problem can be
overcome by configuring static links on these ports. These static links will override any
incorrect dynamically discovered links.

Link type: Ethernet
Discovery techniques:
Inter Chassis Link / Inter Rack Link
Verification Technique: Physical Layer Counters and all of the above discovery techniques except MAC.
6.1.6 LAG
The LAG topology represents a link between two LAG or EtherChannel interfaces that are connected in
the network. The underlying physical links do not have to be discovered for the LAG link to be
discovered.

In the VNE model, the endpoints of the link are indicated in the Data Link Aggregation Container IMO
(IDataLinkAggregationContainer), which points to the LAG or EtherChannel underline ports.
