Link Aggregation

2.1 Example of link aggregation

In a network consisting of seven devices in a line topology, there are two
segments with a particularly large amount of data traffic. You therefore
decide to set up link aggregations in these segments. As well as dividing the
load between a number of lines, you also get increased redundancy reliability
in these segments through the redundant lines.
The link aggregation LATP (Link Aggregation Twisted Pair) consists of
3 twisted pair lines, and the link aggregation LAFO (Link Aggregation Fiber
Optic) consists of 2 glass fiber lines.

The following example describes the configuration of the LATP link aggrega-
tion. For this link aggregation, you provide three free twisted pair ports at
each of the two participating devices. (Connection: Module1 Port1 to Port3).
