Ring/Network Coupling

Use the ring/network coupling to redundantly couple an existing ring (HIPER-Ring, MRP, Fast HIPER-Ring) to another network or another ring. Make sure the coupling partners are Hirschmann devices.

Note: Two-Switch couplingMake sure you have configured a ring (HIPER-Ring, MRP, Fast HIPER-Ring) before setting up the ring/network coupling.

With this dialog you can:

Preparing a Ring/Network Coupling

STAND-BY switch

All devices have a STAND-BY switch, with which you can define the role of the device within a Ring/Network coupling.

Depending on the device type, this switch is a DIP switch on the devices, or else it is exclusively a software setting (Redundancy:Ring/Network Coupling dialog). By setting this switch, you define whether the device has the main coupling or the redundant coupling role within a Ring/Network coupling. You will find details on the DIP switches in the “Installation” user manual.

Note: Depending on the model, the devices have a DIP switch, with which you can choose between the software configuration and the DIP switch configuration. When you set the DIP switches so that the software configuration is selected, the DIP switches are effectively deactivated.

DIP switch/software switch option

According to the option selected
- on “STAND-BY” DIP switch or in the
- Redundancy:Ring/Network Coupling dialog, by making selection in “Select configuration”.
Note: These devices have a DIP switch, with which you can choose between the software configuration and the DIP switch configuration. You can find details on the DIP switches in the User Manual Installation.

Software switch

In the Redundancy:Ring/Network Coupling dialog


Depending on the STAND-BY DIP switch position, the dialog displays those configurations that are not possible as grayed-out. If you want to select one of these grayed-out configurations, change the STAND-BY DIP switch on the device to the other position.

One-Switch coupling
On the device set the 'STAND BY' dip switch to the ON position or use the software configuration to assign the redundancy function to it.

Two-Switch coupling
Assign the device in the redundant line the DIP switch setting “STAND-BY”, or use the software configuration to assign the redundancy function to it.

Note: For reasons of redundancy reliability, do not use Rapid Spanning Tree and Ring/Network Coupling in combination.

Parameter

Meaning

Coupling port

This is the port to which you have connected a redundant connection.
Note: Configure the coupling port and the ring ports, if there are any ring ports, on different ports.
Note: To avoid continuous loops, the device sets the port status of the coupling port to “off” if you switch off the function or change the configuration while the connections are operating at these ports.

Port mode

- active: You have switched the port on.
- stand-by: The port is in stand-by mode.

Port State

- active: You have switched the port on.
- stand-by: The port is in stand-by mode.
- not connected: You have not connected the port.

Partner coupling port

This is the port at which the partner has made its connection. It is only possible and necessary to enter a port if “One-Switch coupling” is being set up.
Note: Configure the partner coupling port and the ring ports, if there are any ring ports, on different ports.

IP address

If you have selected “Two-Switch coupling”, the device displays the IP address of the partner here, once you have already started operating the partner in the network.

Control port

This is the port to which you connect the control line.

Operation

Here you switch the Ring/Network coupling for this device on or off

Information

If the device is a ring manager: The displays in this frame mean:
“Redundancy working”: When a component of the ring is down, the redundant line takes over its function.
“Configuration failure”: You have configured the function incorrectly, or there is no ring port connection.

Redundancy Mode

With the “Redundant Ring/Network Coupling” setting, either the main line or the redundant line is active. Both lines are never active simultaneously.
With the “Extended Redundancy” setting, the main line and the redundant line are simultaneously active if a problem is detected in the connection line between the devices in the connected (i.e., the remote) network. During the reconfiguration period, package duplications may possibly occur. Therefore, only select this setting if your application detects package duplications.

Coupling Mode

Here you define whether the constellation you are configuring is a coupling of redundancy rings (HIPER-Ring, MRP-Ring or Fast HIPER-Ring), or network segments.

Note: If you have configured VLANS, note the VLAN configuration of the coupling and partner coupling ports.
In the Ring/Network Coupling configuration, select for the coupling and partner coupling ports

Note: Independently of the VLAN settings, the device sends the ring coupling frames with VLAN ID 1 and priority 7. Make sure that the device sends VLAN 1 packets tagged in the local ring and in the connected network. This maintains the priority of the ring coupling frames.
Note: If you are operating the Ring Manager and two-Switch coupling functions at the same time, there is the possibility of creating a loop.
Note: The Ring/Network coupling operates with test packets (Layer 2 frames). The devices subscribed always send their test packets VLAN-tagged, including the VLAN ID 1 and the highest VLAN priority 7. This also applies if the send port is an untagged member in VLAN 1.
