Virtual LAN (VLAN)
Introduction
As of firmware version 1.5.0, VLAN is available (in Transparent Bridge mode only).
VLAN can help provide isolation between separate entities who share a single network.
For example, Department A may require access to the radios configuration/Diagnostics, while Department B may only require
access to SCADA information. By implementing VLAN, a virtual network segregation can be implemented to help isolate each
of the departments from one another.
VLAN Configuration
To access the VLAN configuration section, browse to: Setup -> VLAN.
By default, VLAN is disabled. To enable VLAN, select ‘Enabled’. The configurable range of each VLAN is 1 - 4094.
Radio Services VLAN
Management VLAN ID:
Defines the VLAN ID for access to radio management services. Management services include HTTP/S, Telnet, SSH, SNMP
and eDiags. A minimum of one Ethernet interface must be a member of this VLAN to ensure that radio management
services can be accessed. (Default = 1).
SCADA VLAN:
Enables a separate VLAN for radio SCADA services. SCADA services include serial device server & MODBUS gateway. Allows
external serial devices to be connected to COM1/2 and belong to a separate SCADA VLAN. Once enabled, additional
configuration options become available:
- SCADA VLAN ID: SCADA VLAN ID is normally the same VLAN ID defined for SCADA traffic on the Ethernet interface.
Default value is 2.
- SCADA VLAN IP Address: Defines the unique IP address for the Serial Device Server/MODBUS Gateway when they
belong to the SCADA VLAN.
- SCADA VLAN Subnet Mask: Defines the subnet mask for the SCADA VLAN. This determines which IP addresses are
local to the device, and which should be reached through a gateway or router
- COM1 VLAN: Defines the VLAN that the serial device server/MODBUS Gateway using COM1 belongs to. (If SCADA
VLAN is disabled, this defaults to Management)
Management: Service on serial port COM1 will be assigned to the management VLAN
SCADA: Service on serial port COM1 will be assigned to the SCADA VLAN.
- COM2 VLAN: Defines the VLAN that the serial device server/MODBUS Gateway using COM2 belongs to. (If SCADA
VLAN is disabled, this defaults to Management)
Management: Service on serial port COM2 will be assigned to the management VLAN.
SCADA: Service on serial port COM2 will be assigned to the SCADA VLAN.
