How to Use the UTN Server in VLAN Environments

The UTN server supports VLAN (Virtual Local Area Network) according to 802.1Q.
A VLAN divides a physical network into logical subnetworks. Each subnetwork is its own broadcast domain, so
data packets cannot be exchanged between subnetworks. VLANs are used to structure networks and, above all,
to secure them.
Each USB device can be assigned to a VLAN. To transfer VLAN data via the USB ports, you must first enter the
VLANs on the UTN server. After this, the USB ports used for forwarding data must be linked to the specified VLANs.
The access to USB devices can be regulated particularly well with VLAN: a defined
group of network users may use certain USB devices.
Inform yourself on how to implement VLAN in your environment and then set up the
UTN server for it.
• Define a IPv4 Management VLAN  22
• Define a IPv4 Client VLAN  22
• Allocating a IPv4 Client VLAN to a USB Port  23
Define a IPv4 Management VLAN
1. Start the utnserver Control Center.
2. Select NETWORK – IPv4 VLAN.
3. Configure the IPv4 VLAN parameters; table 3.2-1 22.
4. To confirm, click Save.
5. The settings will be saved.
Table 3.2-1: IPv4 management VLAN parameters
Parameters
IPv4 management VLAN
VLAN ID
IP address
Subnet mask
Gateway
Access from any VLAN
Access via LAN (untagged)
Define a IPv4 Client VLAN
1. Start the utnserver Control Center.
2. Select NETWORK – IPv4 VLAN.
3. Configure the IPv4 VLAN parameters; table 3.2-2 23.
Description
Enables/disables the forwarding of IPv4 management VLAN data.
If this option is enabled, SNMP is only available in the IPv4 management VLAN.
ID for the identification of the IPv4 management VLAN (0–4096).
IP address of the UTN server  20.
Subnet mask of the UTN server  20.
IP address of the network's standard gateway which the UTN server uses 
20.
With a gateway, you can address IP addresses from other networks.
Enables/disables the administrative access (web) to the UTN server via IPv4 cli-
ent VLANs.
If this option is enabled, the UTN server can be administrated via all VLANs.
Enables/disables the administrative access to the UTN server via IPv4 packets
without tag.
If this option is disabled, the UTN server can only be administrated via VLANs.
