6.8 VLAN
With VLAN (Virtual Local Area Network) you distribute the data traffic in the
physical network to logical subnetworks. This provides you with the following
advantages:
High flexibility
– With VLAN you distribute the data traffic to logical networks in the
existing infrastructure. Without VLAN, it would be necessary to have
additional devices and complicated cabling.
– With VLAN you specify network segments independently of the
location of the individual end devices.
Improved throughput
– In VLANs data packets can be transferred by priority.
If the priority is high, the device transfers the data traffic of a VLAN
preferentially, e.g. for time-critical applications such as VoIP phone
calls.
– The network load is considerably reduced if data packets and
Broadcasts are distributed in small network segments instead of in the
entire network.
Increased security
The distribution of the data traffic among individual logical networks
makes unwanted accessing more difficult and strengthens the system
against attacks such as MAC Flooding or MAC Spoofing.
The device supports packet-based “tagged” VLANs according to the IEEE
802.1Q standard. The VLAN tagging in the data packet indicates the VLAN
to which the data packet belongs.
The device transmits the tagged data packets of a VLAN exclusively via ports
that are assigned to the same VLAN. This reduces the network load.
The device learns the MAC addresses for every VLAN separately
(independent VLAN learning).
The menu contains the following dialogs:
