A method for determining a topology of an Ethernet ring having a plurality of devices includes disabling a first port of a first device of the plurality of devices, detecting a terminated link at a first port of a second device of the plurality of devices, sending a message to a ring topology generator indicating that the first port of the second device is connected to a previous device relative to the second device, and generating the topology of the Ethernet ring based on (1) the message indicating that the first port of the second device is connected to the previous device relative to the second device and (2) an indication that the first device is the previous device relative to the second device.
