I am using Legato 21.0.5, and I see that the dcS service does support Ethernet as a backend.

Is there any example of how to use AirVantage over Ethernet ?

Actually I do see Ethernet available in the Technology

So perhaps its possible to use the dcs channel for AV like WiFi

I see, the dataConnection service (le\_data.api) does not support this over Ethernet. But the new le\_dcs.api does support the Ethernet channel. AV can only use WIFI or Cell the data connection supported by le\_data.api as I understand it.
