Understanding the Monnit's Ethernet Gateway 4 SNMP Interface

Simple Network Management Protocol (SNMP) is a crucial tool for managing network devices efficiently. By configuring SNMP settings on your gateway, you can monitor and manage network components seamlessly. This article will guide you through the process of adjusting SNMP v1 settings for your gateway.

Inbound IP Range:

Define the range of IP addresses allowed to communicate with the SNMP client. If you have a single device to communicate with, the start and end IP addresses will be the same. However, if you need to exchange information with multiple machines, you'll need a set of different start and end IP addresses.

Inbound Port:

Specify the port number where the server data from the gateway will be received.

SNMP Community String:

The SNMP community string acts as a configurable password for clients within the accepted IP range. Communication will only be allowed if the community string matches. The default string is often set to "public," but it's recommended to change it for security purposes.

Trap Settings:

You have the option to enable or disable trap settings. Enabling traps allows you to receive notifications for events such as authentication failures, new sensor data, and sensor alarms. Specify the trap address (IP address of the SNMP server) and trap port (server port where trap alerts are sent when active).

MIB-II System Configuration Strings:

While not mandatory, setting the contact, name, location, and description strings on the SNMP configuration page can aid in identification and organization.

Interface Data Management:

Set the data expiration time in hours. After this period elapses, data pulled for Modbus and SNMP will be reset to zero.

Simple Network Time Protocol (SNTP) Settings:

SNTP synchronizes computer clocks on a network when the Monnit interface is unavailable. You can choose to enable or disable the SNTP interface. Disabling SNTP will cause your time settings to be synchronized through iMonnit. Specify the SNTP IP address (server from which time is pulled).

Miscellaneous System:

SNMP Client Configuration:

Download the MONNIT-EGW4.mib file from monnit.com, which provides proper field names for EGW4-specific data points and sensor data in your SNMP client.

Data Interpretation:

After loading the MONNIT-EGW4.mib file to your SNMP client, you can poll data in various table view formats configured by Monnit. Data presented in the EGW4SensorInfoTranslatedFormat Table will be converted into usable information, while other tables will display raw data. For further assistance in interpreting raw data, contact Monnit directly for the SNMP Data Interpretation document.

By following these instructions, you can effectively configure SNMP v1 settings for your gateway, ensuring efficient network management and monitoring.
