The user does not need to configure any of the NPort 6000 units as the master to use Turbo Ring or Turbo Ring
V2. If none of the NPort 6000 in the ring is configured as the master, then the protocol will automatically assign
master status to one of the NPort 6000 units. In fact, the master is only used to identify which segment in the
redundant ring acts as the backup path. In the following subsections, we explain how the redundant path is
selected for rings configured for Turbo Ring, and Turbo Ring V2.
Determining the Redundant Path of a “Turbo Ring” Ring
In this case, the redundant segment (i.e., the segment that will be blocked during normal operation) is
determined by the number of EDS units that make up the ring, and where the ring master is located
When the number of NPort 6000 units in the Turbo Ring is even.
If there are 2N NPort 6000 units (an even number) in the
Turbo Ring, then the backup segment is one of the two
segments connected to the (N+1)st NPort 6000 (i.e., the
NPort 6000 unit directly opposite the Master).
When the number of NPort 6000 units in the Turbo Ring is odd.
If there are 2N+1 NPort 6000 units (an odd number) in
the Turbo Ring, with NPort 6000 units and segments
labeled counterclockwise, then segment N+1 will serve
as the backup path.
For the example shown here, N=1, and therefore N+1=2.
