In this example, the devices are connected by using device-level ring (DLR)
topology. DLR topology is fault redundant. For example, if a device in the ring
is disconnected, the rest of the devices in the ring continue to maintain
communication.
• Up to 64 devices in the DLR configurations.
• All Devices in a DLR ring should have dual-port connectivity or be
connected in the ring by using a 1783-ETAP module.
