Enable the "Diagnostic interrupts" option, if you want diagnostic interrupts relating to the
MRP status on the local CPU to be output.
The following diagnostic interrupts can be generated:
● Wiring or port error
Diagnostic interrupts are generated if the following errors occur at the ring ports:
– Connection abort on a ring port
– A neighbor of the ring port does not support MRP.
– A ring port is connected to a non-ring port.
– A ring port is connected to the ring port of another MRP domain.
● Status change active/passive (redundancy manager only)
If the status changes (active/passive) in a ring, a diagnostics interrupt is generated.
Parameter assignment of the redundancy is not set by STEP 7 (redundancy alternatives)
This option only affects switches. Select this option if you want to set the properties for
media redundancy using alternative mechanism or tools such as Web based Management
(WBM), CLI or SNMP.
If you enable this option, existing redundancy settings from WBM, CLI or SNMP, are retained
and are not overwritten. The parameters in the "MRP configuration" box are then reset and
grayed out. The entries then have no meaning.
SCALANCE X switches support not only ring redundancy within a ring but also redundant
linking of rings or open network segments (linear bus). In the redundant link, rings are
connected together over Ethernet connections. This is achieved by configuring a
master/slave device pair in one ring so that the devices monitor each other and, in the event
of a fault, redirect the data traffic from the normally used master Ethernet connection to the
substitute (slave) Ethernet connection.
