Setting up SNMP for remote management of the FATBOX G3 Gateway

SNMP (Simple Network Management Protocol) is integrated in our FATBOX G3 to enable remote monitoring of gateway’s operating conditions.


This application note explains the steps to enable the SNMP agent in the FATBOX G3 IoT Gateway (either cellular 4G, LTE, 3G or Ethernet WAN models supported) for remote centralised monitoring and management of the device.

Step 1: Enable SNMP in the FATBOX G3.

Securely login to the FATBOX G3 web console and go to the ‘SNMP’ menu.

Do take note of the following:

  • If SNMP is accessed only via local network LAN, do not enable the ‘SNMP access from WAN’ setting for improved security.

To activate the SNMP settings click on Update and initiate a Reboot (e.g. via Management menu).

Step 2: Add a new SNMP monitoring service (e.g. Nagios XI)

For this set up example we are using a SNMP monitoring service like Nagios XI to provide an interface for our users to manage.

We start by creating an account and adding in our designated Device address and Host name.

Next we will need to specify the SNMP version, SNMP port and SNMP community string you are using.

The current FATBOX G3 firmware supports both SNMP v1 and v2c.

  • SNMP version 1 is easy to set up and only requires a plaintext community. However it only supports 32 bit counters and not 64 bit counters.

  • SNMP version 2c is identical to version 1 but supports for 64 bit counters which enable interfaces to poll more accurate data. 

Step 3: Add Object Identifiers (OID) to define each agent for the manager service

Specify the OIDs that you'll like to monitor via the SNMP service using the reference chart below.

You can also download the PDF version of our OID list here.

For Example:

To monitor the G3 CPU Temp, the OID is .

Once the SNMP settings has been updated in the Network Management Software, the user would be able to monitor remote gateway and set required alarm or triggers.


  • Integrated device server for scheduled poll and read from attached equipment

  • Multi-port support - RS-232/RS-485 (e.g. MODBUS), Ethernet, CANBus and USB (for Zigbee transceiver).

  • Azure IoT Hub client to integrate with your Azure cloud resources  

  • Persistent LTE and 3G data connection with integrated watch-dog

  • User scripts supported for local logic and out-of-band alert messages 

  • Model with on-board RTC 

  • SNMPv2 for management

  • Wide power supply 5~30VDC (12/24V) ensures stability of operation

  • Industrial temperature -40C to 75C and robust aluminium enclosure for durability
