Network structures
6
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
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
●
Aggregation of interfaces or connections between devices to increase the data
transmission rate and reliability (link aggregation, port aggregation)
●
Detection and monitoring of parallel connections or loops in an Ethernet network by
setting up a tree structure (loop detection)
●
Improved reliability by adapting the tree structure if transmission is disrupted (Spanning
Tree)
●
Splitting up of the network into smaller units that are connected together via managed
connection pairs (standby connection)
6.1
VLAN
This section describes commands for configuring and managing virtual networks (VLANs).
Commands for configuring and managing private VLANs are also described.
With a private VLAN (PVLAN) you can divide up the layer 2 broadcast domains of a VLAN.
