Turbo Ring with odd number switches
Master
Segment N+1
If the number of Ethernet switches in the Turbo
Ring is 2N+1 (an odd number), the backup
segment is the (N+1)st segment counting
counterclockwise.
For the example shown here, N=1, so that
N+1=2.
Determining the Redundant Path for Turbo Ring V2
Master
For
Turbo Ring V2
, the backup segment is the
segment connected to the 2nd redundant port on
the master.
Please refer to
Configuring Turbo Ring V2
later in this chapter.
Ring Coupling Configuration
For some systems, it may not be convenient to connect all devices in the system in a single
redundant ring, since some devices could be located in a remote area. For these systems,
Ring
Coupling
can be used to group devices into smaller redundant rings that communicate with each
other.
ATTENTION
In a VLAN environment, the user must set
Redundant Port
Coupling Port
and
Coupling
Control Port
to join all VLANs, since these ports act as the
backbone
to transmit all packets of
different VLANs to the different PT series Ethernet switches.
