
Group ID: This setting is relevant if you want to apply static link aggregation. Combine ports into
one group for this by entering the same group ID. This setting will not be required for dynamic
link aggregation.

Mode: This setting is relevant for dynamic LACP. The LACP protocol is active for the port in
active mode. The LACP protocol is only active for the port in passive mode if the remote station
of the port connection is also in passive mode. The protocol is sent to bridge a link failure
without packet loss. At least one side of the link must be configured as the active part with
dynamic link aggregation.

Port priority: This setting is relevant for dynamic LACP. If another port is required for a logical
connection, the free dynamic port with the highest port priority is selected. The lower the
number, the higher the priority.
3.9 Redundancy
This page provides an overview of the available redundancy protocols and their status. It is not possible to
have multiple redundancy protocols running at the same time, so only one can be enabled. With the help
of the edit buttons, you can access the protocols and carry out the configuration there.
The following protocols are available:

MRP: The media redundancy protocol is a ring protocol for highly available networks, which is
achieved by inserting redundant paths.

RSTP: The rapid spanning tree protocol is a standardised method to manage mixed structures in
the network and contains a mechanism for automatic reconfiguration.

MSTP: MSTP generally can create a separate spanning tree for each VLAN.
The use of redundancy protocols guarantees your network increased reliability and availability in the event
of a fault. The failure of a component is absorbed, and the subscribers not affected by the failure can
continue to communicate.
MRP
The media redundancy protocol is a ring protocol for highly available networks. The high availability is made
possible by redundant communication paths, which are set to shutdown state during normal operation. The
subscribers connected in the network operate in a line topology, although it is physically a ring. In the event
of a fault, communication can take place via the previously disabled path after a very short recovery time.
MRP uses a redundancy manager that tests the continuity of the ring by means of special test packets and
reconfigures the network in the event of a fault and informs the subscribers accordingly. The guaranteed
reconfiguration time, with up to 50 devices in the ring, is 200 ms. The reconfiguration time usually is less
than 50 ms in a typical application.
