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

The proprietary Turbo Ring protocol was developed by Moxa to optimize communication redundancy and achieve a faster recovery time on the network.

Turbo Ring protocol identifies one switch as the “master” of the network, and then automatically blocks packets from traveling through any of the network’s redundant loops. In the event that one branch of this ring gets disconnected from the rest of the network, the Turbo Ring protocol automatically readjusts the ring (if possible) so that the part of the network that was disconnected reestablishes contact with the rest of the network.

Initial Setup

1. Select any two ports as redundant ports.

2. Connect the redundant ports to form the Turbo Ring

You do not need to set the Master to use Turbo Ring. Master is only needed to identify which segment acts as the backup path. The actual topology of the redundant ring, i.e., which segment will be blocked, is determined by the number of EDS-726 switches that make up the ring, and where the “Ring Master” is located.
