connecting to a hardwired ethernet device

[Geoffrey Leach]

This is a new Fedora 19 install.

The install correctly detected the ethernet port.

ifconfig sees em1, and the configuration data is correct

There is a device plugged into the port, which monitors its ethernet port. (The device is known to work otherwise)

So, somehow I'm supposed to specify the topology of the connection.

Any suggestions on how to go about debugging the connection?  Thanks.
