Release 8.0 09/2019
Note: You configure optical ports without support for autonegotiation (automatic configuration) with
100 Mbit/s full duplex (FDX) or 1000 Mbit/s full duplex (FDX).
Note: You configure optical ports without support for autonegotiation (automatic configuration) with
100 Mbit/s full duplex (FDX).
Note: Configure every device of the MRP-Ring individually. Before you connect the redundant line,
verify that you have completed the configuration of every device of the MRP-Ring. You thus help
avoid loops during the configuration phase.

You deactivate the flow control on the participating ports.
If the flow control and the redundancy function are active at the same time, it is possible that the
redundancy function operates differently than intended. (Default setting: flow control
deactivated globally and activated on every port.)

Disable Spanning Tree on every device in the network:

Enable MRP on every device in the network:
In the Command Line Interface you first define an additional parameter, the MRP domain ID.
Configure every ring participant with the same MRP domain ID. The MRP domain ID is a sequence
of 16 number blocks (8-bit values).
