Determining the Redundant Path of a "Turbo Ring V2" Ring
If there are 2N IE-SW units (an even number) in
the "Turbo Ring" ring, then the backup segment
is one of the two segments connected to the
(N+1) st IE-SW (i.e., the IE-SW unit directly
opposite the master).
If there are 2N+1 IE-SW units (an odd number)
in the "Turbo Ring" ring, with IE-SW units and
segments labeled counterclockwise, then
segment N+1 will serve as the backup path.
For the example shown here, N=1, so that
N+1=2.
For a "Turbo Ring V2" ring, the backup segment
is the segment connected to the 2nd redundant
port on the master.
See Configuring "Turbo Ring V2" in the
Configuring "Turbo Ring" and "Turbo Ring
V2" section below.
