A method of testing a primary device for two-way communication between the primary device and one or more other devices in communication therewith in a network is disclosed. The method includes inserting into an echo packet an originating device identifier in an originating device field and a primary device identifier in a primary device field, and transmitting the echo packet from the primary device. Two-way communication is detected if a reply packet received at the primary device contains the originating device identifier in the originating device field and the primary device identifier in the primary device field. A system for testing a primary device for two-way communication between the primary device and neighbor devices coupled to the primary device is also disclosed.
