If it is required that a network connection is "redundant" on the layer 2 level - does that mean I need to use the "teaming" feature of certain network adapters (provided by special drivers for certain intel adapters for example)?
Do I get this right: With this "teaming", both network adapters operate on the same ip address, if one cable fails the connection will stay alive using the second cable? Client software does not notice anything of that, it only sees one ip address?
