Creating And Configuring The Link Aggregation - Hirschmann RS20 Programming Manual

Link Aggregation
2.1.1 Creating and configuring the
link aggregation
Note: A link aggregation always has exactly two devices.
You configure the link aggregation on each of the two devices involved. Dur-
ing the configuration phase, you connect a maximum of one connection line
between the devices. This is to avoid loops.
Under Basic Settings:Port Configuration, you configure all
three connections so that the transmission speed and the duplex settings
of the participating ports on both devices are matching.
Among the devices involved in a link aggregation, you define that device
that has the most devices between itself and the device to which the
configuration PC/(NMS network management station) is connected. You
begin the configuration at this device, otherwise the Link Aggregation
Control Protocol (LACP) can block ports and disconnect devices from the
network, so that they cannot be configured any more.
In the example below
on device 3, then on device 2. If you accidentally disconnect device 3
from the network, you can access it again by selecting "Allow static link
aggregation" in the Redundancy: Link Aggregation dialog, or by
activating this option via the CLI.
