The System.SnmpTrapProvider data source module type is used to return SNMP traps as a System.SnmpData data type.

Warning

The System.SnmpTrapProvider module is included in System Center Operations Manager 2012 for backward compatibility only. Its functionality has been superseded by the System.NetworkManagement.SnmpTrapProvider module.

Usage

Use this module to either receive SNMP trap events from within a workflow such as a rule or monitor.

Parameters

The System.SnmpTrapProvider module supports the following configuration parameters:

Parameter Type Description

IP

String

Specifies the IP address of the SNMP managed entity from which the traps originate.

CommunityString

String

Contains the SNMP Community String.

AllTraps

Boolean

Specifies whether all traps from the target device should be sent to Operations Manager.

Version

String

Optional. Specifies the SNMP version. The default value is “2”. To perform an SNMP v1 transaction, the value must be “1”.

OIDProps

Complex

Contains a list of OIDs to register for traps when AllTraps is set to false.

AllTraps

When set to true, the System.SnmpTrap.EventProvider module is configured to send all traps from the targeted device to Operations Manager. When it is set to false, an OIDProps element with at least one OIDProp element must be provided.

<AllTraps>true</AllTraps>

OIDProps

Contains a list of at least one OIDProp element. Each OIDProp element represents an OID that traps from the targeted device will contain. If AllTraps is set to true, this element is not necessary. It should be noted that if this element does contain at least one OIDProp element, AllTraps will be ignored.

<OIDProps>
   <OIDProp>1.3.6.1.2.1.4.1.0</OIDProp>
</OIDProps>

Composition

The System.SnmpTrapProvider module is a native module.

The System.SnmpTrapProvider module wraps portions of the WinSNMP API. For a deeper understanding of how the module works internally, see the WinSNMP API topic.

The following errors can occur from within the System.SnmpTrapProvider module.

Exception Reason

11001

An SNMP GET message failed.

11002

An SNMP SET message failed.

11003

An error occurred when receiving an SNMP message, and the received varbind status was not valid.

11004

The module failed to retrieve PDU data.

11006

The module was unable to initialize the SNMP session.
Module Type Usage

System.SnmpScanProbe

Performs SNMP GET actions in the context of an IP range. The module returns a System.SnmpData data type.

System.SnmpScanProbe

Module Type Library Usage

System.SnmpTrapEventProvider

System.Snmp.Library

Returns SNMP traps as a device specific System.Event.Data data type.

Sample

The following example shows how you can set up a rule to receive an SNMP cold start trap from an SNMP network device. When the trap is received, an alert is generated.
