– If no manager function module is present during the boot process and the MRP manag-
er is enabled in the saved configuration, the device activates a “safe state”, in which one
of the ring ports is set to blocking mode to prevent loop generation. An error message
appears, which would also be displayed in the event of a ring error, informing the user
of this configuration error. After inserting the manager function module, the manager
can be re-enabled manually or a reboot executed.
– If a manager function module is removed during runtime, the MRP manager can no lon-
ger be selected.
– If a manager function module is removed while the MRP manager is active, the mode
remains active until the device is restarted or is switched to another mode (MRP client,
disabled).

Figure 5-9 Example of an MRP ring
5.2.2.2 Redundancy configuration
The “MRP Configuration” web page is used to configure the protocol parameters. The fol-
lowing configuration parameters are displayed:
– Device role (disabled, MRP client or MRP manager)
– Selection of the ring ports that are integrated in the MRP ring
Make sure that the topology used does not contain an invalid mixture of RSTP and MRP,
e.g., by additionally coupling two of the devices through an RSTP connection rendering
them redundant.
