SNMP for Ethernet Gateways

The following are step-by-step instructions for implementing SNMP using the Ethernet Gateway Version 4 (EG4). These instructions are intended for SNMP versions 1 and 2. The Version 4 Gateway does support version 3 SNMP. For details on version 3 implementation please contact 

Data Output from SNMP Gateways

Packet Power Gateways collect data from Packet Power wireless monitoring nodes and aggregate the data for transmission by SNMP, Modbus TCP/IP and directly to the Packet Power EMX monitoring portal. Note that the Gateway can support transmission of data via either SNMP or Modbus TCP/IP while simultaneously serving data to the EMX portal.

Required Files and Tools for SNMP

MIB Files

  • MIB files can be downloaded directly on the Gateway.

See: SNMP for Ethernet Gateways | Downloading-the-Standard-MIB-File

A MIB File Browser

See: Using the iReasoning MIB Browser

Configured EG4 Gateway

  • The Gateway is configured and communicating with the wireless nodes.

See: Network Configuration

  • The Gateway has a license for SNMP.

See: Console - System

Accessing the Gateway Console

Make sure your Gateway is configured with an IP address and accessible on your network. The Gateway must be connected to a switch /router on an accessible network.

It may not be accessible directly through a PC Ethernet to Gateway connection. For Gateway network configuration instructions follow this link.

  1. Enter the IP address of the Gateway on any browser to access the Gateway Console

  2. Make sure SNMP is listed as a licensed feature. If not see the licensing section on how to add a license

  3. Make sure that the system is communicating properly with the monitoring nodes as indicated by a green status light

  4. Click the link under Wireless Mesh to see monitoring nodes that are currently communicating with the Gateway

  5. SNMP Data will be able to be viewed through the SNMP data link; this light will be green once the SNMP agent is enabled

Accessing the MIB files from Gateway Console

MIB files can be downloaded directly from the Gateway Console.  There are two MIB files. The standard EG4 file is for use in standard SNMP applications. The VIP MIB file is used when using Virtual IP addresses for each monitoring node instead of the standard 16 digit GUID embedded in the OID. 

If the link is not available on the console this may require that the Gateway firmware be upgraded to version 1.12 or higher

Downloading the Standard MIB File

On the Gateway console go to Data Destinations>SNMP on the left menu and then click on the standard MIB file. 

Downloading the MIB File for Use With Virtual IP Addressing

On the Gateway console go to Data Destinations>SNMP>Nodes on the left menu and then click to download the MIB file. 

Viewing monitoring node readings on the Gateway Console

  1. Confirm that monitoring nodes are active and returning data to the Gateway by selecting  the “Monitoring Data” tab; this will display all connected nodes

  2. Click on the “readings” icon to expose the real time readings for a specific monitoring node

Uploading an SNMP license to the Gateway

  1. To activate a product license, select the license file by clicking on the “choose file” button under “Select License File” in the “System” menu

  2. Click on the “Upload” button and point to the location of the license provided by Packet Power

A reboot of the device will be required to make the license effective. The reboot tab can be found under the “System” menu.

In the event that SNMP is not a licensed feature you will need to obtain a license from Packet Power  

Enabling and configuring the SNMP Agent

  1. Click on the SNMP tab under the Data Destinations tab on the Gateway console

  2. Make sure SNMP is enabled in the check box

  3. Select the correct SNMP version. This guide is for SNMP V1 and V2; for SNMP V3 implementation see the SNMP 3 guide

  4. Set the Agent port to 161 or as needed

  5. The Community read string (used for authentication) should be “public”

  6. Click “Save” to save settings

The SNMP status light in the left menu will be green indicating the onboard SNMP agent is active
