2 Ring Redundancy
The concept of ring redundancy allows the construction of high-availability,
ring-shaped network structures.
With the help of the RM (Ring Manager) function, the two ends of a backbone
in a line structure can be closed to a redundant ring. The ring manager keeps
the redundant line open as long as the line structure is intact. If a segment
fails, the ring manager immediately closes the redundant line, and line
structure is intact again.

Redundanz L2B
Release 5.0 04/09
If a section is down, the ring structure of a
X HIPER-(HIGH PERFORMANCE REDUNDANCY) Ring with up to 50 de-
vices typically transforms back to a line structure within 80 ms (setting:
standard/accelerated).
X MRP (Media Redundancy Protocol) Ring (IEC 62439) of up to 50 devices
typically transforms back to a line structure within 80 ms (adjustable to
max. 200 ms/500 ms).
Device requirements for using the HIPER-Ring function:
X Within a HIPER-Ring, you can use any combination of the following
devices:
–RS1
– RS2-./.
– RS2-16M
–RS2-4R
– RS20, RS30, RS40
– RSR20, RSR30
– OCTOPUS
–MICE
–MS20, MS30
–Power MICE
– MACH 100
– MACH 1000
– MACH 3000
– MACH 4000
X Within an MRP-Ring, you can use devices that support the MRP protocol
based on IEC62439.
Note: Enabled Ring Redundancy methods on a device are mutually exclusive at any one time. When changing to another Ring Redundancy method,
deactivate the function for the time being.
Note: The following usage of the term “ring manager” instead of “redundancy
manager” makes the function easier to understand.

2.1 Example of HIPER-Ring
A network contains a backbone in a line structure with 3 devices. To increase
the redundancy reliability of the backbone, you have decided to convert the
line structure to a HIPER-Ring. You use ports 1 and 2 in module 1 of the
devices to connect the lines.
Figure 3: Example of HIPER-Ring
RM = Ring Manager
—— main line
- - - redundant line
The following example configuration describes the configuration of the ring
manager device (1). The two other devices (2 to 3) are configured in the
same way, but without activating the ring manager function. Select the
“Standard” value for the ring recovery, or leave the field empty.
Note: You cannot configure devices with L2B software as ring managers.
You can exlusively use these devices as members of the redundant ring.

Note: Configure all the devices of the HIPER-Ring individually. Before you
connect the redundant line, you must complete the configuration of all the
devices of the HIPER-Ring. You thus avoid loops during the configuration
phase.

2.1.1 Setting up and configuring the HIPER-Ring
Set up the network to meet your requirements.
You configure all 6 ports so that the transmission speed and the duplex
settings of the lines correspond to the following table:
Bit rate 100 Mbit/s 1000 Mbit/s
Autonegotiation
(automatic configuration)
off on
Port on on
Duplex Full –
Table 2: Port settings for ring ports
Select the Redundancy:Ring Redundancy dialog.
Under “Version”, select HIPER-Ring.
Define the desired ring ports 1 and 2 by making the corresponding
entries in the module and port fields. If it is not possible to enter a
module, then there is only one module in the device that is taken
over as a default.
Display in “Operation” field:
– active: This port is switched on and has a link.
– inactive: This port is switched off or it has no link.

Release 5.0 04/09
Note: Deactivate the Spanning Tree protocol on the ports connected to the
HIPER-Ring because Spanning Tree and Ring Redundancy affect each other. If you enable the HIPER-Ring function by means of the DIP switch,
RSTP will be disabled automatically.
Now you connect the line to the ring. To do this, you connect the two
devices to the ends of the line using their ring ports.
Figure 4: Ring Redundancy dialog
Click on “Set” to temporarily save the entry in the configuration.
The displays in the “Information” frame mean
– “Redundancy existing”: One of the lines affected by the function can
fail, whereby the redundant line will then take over the function of the
failed line.
– “Configuration failure”: The function is incorrectly configured or there
is an error in the ring port connection.

2.2 Example of MRP-Ring
A network contains a backbone in a line structure with 3 devices. To increase
the redundancy reliability of the backbone, you have decided to convert the
line structure to a ring redundancy. In contrast to the previous example,
devices from different manufacturers are being used which do not all support
the HIPER-Ring protocol. All the devices have MRP as the ring redundancy
protocol, so you decide to use MRP. You use ports 1 and 2 in module 1 of
the devices to connect the lines.

The following example configuration describes the configuration of the ring
manager device (1). You configure the two other devices (2 to 3) in the same
way, but without activating the ring manager function. This example does not
use a VLAN. You have entered 200 ms as the ring recovery time, and all the
devices support the advanced mode of the ring manager.
