SNMP Configuration Parameters

Introduction

Parameters on the SNMP configuration tab are divided into four categories:

the IP addresses of SNMP manager devices
SNMP agents
the community names
security

NOTE: Only 7-bit ASCII characters can be used in the character string entry fields.

IP Address Managers

This zone allows you to complete the IP addresses of the SNMP managers. The modules authorize a maximum of two managers.

These addresses are used during possible transmission of events (TRAP). The transmission of supervised data is detailed at the topic SNMP.

Agent

This zone allows the localization and identification of an agent from the SNMP manager.

It comprises two fields:

The Location (SysLocation) field: indicates the physical location of the device (32 characters maximum).
The Contact (SysLocation) field: indicates the person to contact for device management and the method of contact (strings of 32 characters maximum).
If you prefer to have this information assigned by an SNMP Manager tool for network management, check the SNMP Manager box.

Community Name

This zone is used to define community names for the Set, Get and Trap utilities. It comprises three fields:

The Set field defines the community name for the Set utility (strings of 16 characters maximum). The default value of the field is Public.
The Get field defines the community name for the Get utility (strings of 16 characters maximum). The default value of the field is Public.
The Trap field defines the community name for the Trap utility (strings of 16 characters maximum). The default value of the field is Public.

The purpose of these fields is to define the access rights for the MIB objects of the SNMP agent (local module) in relation to requests sent by the manager.

Example: If the manager sends a SetRequest request with the community name Test and the module has the community name Public, the request is not executed.

Security

CAUTION

UNEXPECTED NETWORK BEHAVIOR - SNMP PARAMETERS RESET

The SNMP manager is able to modify the value of certain configurable parameters(Enabling "Authentication failure," Location, Contact. etc.).

the SNMP Manager box is not checked and there is a cold start, warm restart, or application download, the initially configured values are restored.

Failure to follow these instructions can result in injury or equipment damage.

This zone contains the Enable "Authentication Failure" trap check box.

Checking this box allows you to validate the transmission of an authentication failure event (TRAP) from the SNMP agent to the configured manager.

In this way, the agent warns the manager that the request has been refused following an identification error (community name configured in the manager is different from the one configured in the agent).
