Network Structures - Siemens SCALANCE XM-400 Configuration Manual

Network structures

This part contains the sections that describe the commands for configuring and managing
various network structures.
The following technologies are available:
● The establishment of independent structures even across the boundaries of subnets
● Aggregation of interfaces or connections between devices to increase the data
● Detection and monitoring of parallel connections or loops in an Ethernet network by
● Improved reliability by adapting the tree structure if transmission is disrupted (Spanning
● Splitting up of the network into smaller units that are connected together via managed

using virtual networks (VLANs)
This can result in the following advantages:
– Administration:
Devices can be grouped together to form a logical units regardless of their physical
location
– Performance:
By prioritizing, time-critical data (process data, streams) can be given priority for
transfer
– Security:
The transition between VLANs can only be controlled by an administrator
