Dell NativeEdge: How to interpret interface output from NativeEdge Service Console Client

After starting the NativeEdge Service Console client tool and entering the MAC address of the NativeEdge-enabled Device, the following message is displayed:
 

Multiple interfaces are up. Select the valid interface from the device:
(after this follows a list of NICs and their MAC addresses)

To proceed, select the relevant interface that is also on the same Layer 2 network as the NativeEdge Endpoint.

The NativeEdge Service Console uses Layer 2-based connectivity between the client and the NativeEdge Endpoint. If the client machine where the service console tool is being started from, has multiple networks configured, the user is provided with an option to choose the network interface on the client machine which will be used for connecting with the NativeEdge Endpoint, that is, select the interface on the client machine that is on the L2 network as the NativeEdge Endpoint.
