NOTE
Port trunking and Turbo Ring can be enabled simultaneously to form a backbone. Doing so will
increase the bandwidth of the backbone, and also provide redundancy. For example, suppose that
two physical ports, 1 and 2, are trunked to form trunk group Trk1, and then Trk1 is set as one
Turbo Ring path, if port 1 gets disconnected, the remaining trunked port, port 2, will share the
traffic. If port 1 and port 2 are both disconnected, Turbo Ring will create the back up path within
300 ms.
The Turbo Ring Concept
Moxa developed the proprietary Turbo Ring protocol to optimize communication redundancy and
achieve a faster recovery time on the network.
The Turbo Ring and Turbo Ring V2 protocols identify one switch as the master of the network,
and then automatically block packets from traveling through any of the network’s redundant loops.
In the event that one branch of the ring gets disconnected from the rest of the network, the protocol
automatically readjusts the ring so that the part of the network that was disconnected can
reestablish contact with the rest of the network.
Initial setup of a “Turbo Ring” or “Turbo Ring V2” ring
1. Select any two ports as redundant ports.
2. Connect the redundant ports to form the
Turbo Ring.
