When configuring P-Ring, through the web manager or CLI, simply check “Enable P-Ring”, Then, select the ring ports and specify whether the switch performs as the “root” ( “Manager” ) or “ Client”. That's it! You can now install a safe, loop free ring network. A fiber optic ring network is a physical or logical network topology where devices (usually switches) are connected in a closed-loop using fiber optic cables. Each node is connected to two other nodes, forming a ring-like structure. If one. Device Level Ring (DLR) is a Layer 2 protocol that enables redundancy in a ring topology, providing fast network fault detection and reconfiguration for industrial networks. DLR is an EtherNet/IP™ protocol that is defined by the Open DeviceNet® Vendors' Association (ODVA). Single Ring Dual Ring Coupling Dual Homing Chain Balancing Chain Before. The fiber optic ring redundancy design for industrial Ethernet switches is precisely engineered to address this pain point—achieving millisecond-level fault self-healing through the synergy of physical ring architecture and intelligent protocols, thereby constructing the "self-healing heart" of. Looking at the basics of setting up a redundant ring with either fibre or copper links. It's one of the options discussed in extended chat with @zac67 Essentially there were two requirements for what I needed to do: A Bi-Directional technology.
