Configuring the SNMP Agent

Description

The Ethernet communication module includes an SNMP v1 agent. An SNMP agent is a software component running on the communication module that allows access to the module's diagnostic and management information via the SNMP service.

SNMP browsers, network management software, and other tools typically use SNMP to access this data. In addition, the SNMP agent can be configured with the IP address of up to two devices—typically PC's running network management software—to be the target of event driven trap messages. These trap messages inform the management device of events such as cold start, and detected authentication failures.

Use the SNMP page to configure the SNMP agent in the communication module. The SNMP agent can connect to and communicate with up to 2 SNMP managers as part of an SNMP service. The SNMP service includes:

authentication checking, by the Ethernet communication module, of any SNMP manager that sends SNMP requests
management of event, or trap, reporting by the module

The SNMP page looks like this:

NOTE: Refer to the topic Configuring Properties in the Device Editor for instructions on how to edit properties.

Viewing and Configuring SNMP Properties

NOTE: The sysName SNMP parameter is neither editable nor visible in the Control Expert Ethernet Configuration Tool software. By default, the sysName is set to the Ethernet communication module part number.

The following properties can be viewed and edited in the SNMP page:

Property	Description
IP Address Managers:
IP Address Manager 1	The IP address of the first SNMP manager to which the SNMP agent sends notices of traps.
IP Address Manager 2	The IP address of the second SNMP manager to which the SNMP agent sends notices of traps.
Agent:
Location	The device location (32 characters maximum)
Contact	Information describing the person to contact for device maintenance (32 characters maximum)
SNMP Manager	Select either: TRUE: the Location and Contact information are editable in this page FALSE: Location and Contact settings are not editable in this page
Community Names:
Get	Password required by the SNMP agent before executing read commands from an SNMP manager. Default = public.
Set	Password required by the SNMP agent before executing write commands from an SNMP manager. Default = public
Trap	Password an SNMP manager requires from the SNMP agent before the manager will accept trap notices from the agent. Default = public
Security:
Enable Authentication Failure Trap	TRUE causes the SNMP agent to send a trap notification message to the SNMP manager if an unauthorized manager sends a Get or Set command to the agent. Default = FALSE.
