VLANs provide extra security:
Devices within each VLAN can only communicate with
other devices on the same VLAN. If a device on VLAN
Marketing
needs to communicate
with devices on VLAN
Financ
e, the traffic must pass through a routing device or Layer 3
switch.
VLANs help control traffic:
With traditional networks, congestion can be caused by
broadcast traffic that is directed to all network devices, regardless of whether or not they need
it. VLANs increase the efficiency of your network because each VLAN can be set up to
contain only those devices that need to communicate with each other.
Using Virtual LANs
Port-based VLANs and the Moxa EtherDevice Switch
The EDS-405A/408A supports Port-based VLAN. When using this function, you must first define
which ports should join the VLAN. Once set, devices can be moved around the network without
affecting to which VLAN the device is connected.
For example, to separate port 2 and port 3 to different groups due to security issues, click
VLAN
Settings
and then select
Port-Based VLAN
. For this example, place port 2 on VLAN 1 and port 3
on VLAN 2. Ports 2 and 3 will not be able to communicate with each other, even though they are
on the same switch.
NOTE
Port-based VLAN settings only affect one switch. The EDS-405A can have a maximum of 5
VLAN settings and the EDS-408A can have a maximum of 8 VLAN settings.
NOTE
The Turbo Ring Ports and Coupler Ports will be added to all VLANs if you enable the “Turbo
Ring DIP Switch” and set the Turbo Ring DIP Switch from
OFF
to
ON
.
NOTE
If you enable the Hardware DIP Switch for Turbo Ring and set the Turbo Ring DIP Switch from
ON
to
OFF
, then the Ring Ports and Coupler Ports that are added to all VLANs will be restored
to their previous software settings. (For details on how to do this, refer to “Configuring Basic
Settings—Turbo Ring DIP Switch.”)
