Send SNMP Trap

  • Artikel

The Send SNMP Trap activity will raise an SNMP event that can be detected by a network systems manager application. By using an enterprise identifier of a known network device, you can send SNMP Traps on behalf of a network device in your system. Use the Send SNMP Trap to create events for runbooks that need to be tracked using an SNMP monitoring product.

Configure the Send SNMP Trap Activity

Before you configure the Send SNMP Trap activity you need to determine the following:

  • IP address of the device where you will send your SNMP trap

  • Identifiers of the trap

  • The SNMP version you will use

  • The agent address you want to identify as the sender of the SNMP trap information

Note

You can't set individual security credentials for this activity. It will run under the service account configured for the Runbook Service on the Runbook server where the instance of the activity is running. This account must have the authority to access the resources and perform the actions required by this activity.

Use the following information to configure the Send SNMP Trap activity.

You can also add more information to the SNMP trap. Each item that you add becomes a published data item.

Enterprise identifier Specify the enterprise identifier of the event being raised by the Send SNMP Trap activity.
Generic identifier Specify the generic identifier of the SNMP trap. There are six options available:

coldStart(0): Select to signify a cold start of the network device. This option has a numerical value of 0.

warmStart(1): Select to signify a warm start of the network device. This option has a numerical value of 1.

linkDown(2): Select to signify a severed connection to the network device. This option has a numerical value of 2.

linkUp(3): Select to signify a re-established connection to the network device. This option has a numerical value of 3.

authenticationFailure(4): Select to signify a failed SNMP authentications to the network device. This option has a numerical value of 4.

egpNeighborLoss(5): Select to signify a lost EGP peer connection to the network device. This option has a numerical value of 5.

enterpriseSpecific(6): Select to specify an enterprise-specific id. This option has a numerical value of 6. You must specify this option to specify a specific identifier.
Specific identifier Type the enterprise-specific identifier for the SNMP trap. This setting becomes active when you select the enterpriseSpecific(6) option of the Generic identifier box.
SNMP Version Select the SNMP version to use when generating the SNMP trap.
Community string Type the community string that will be used to authenticate against the network device. This field is case-sensitive and supports only alphanumeric characters.

The Send SNMP Trap activity does not verify the content of community strings, nor whether the strings are received. It sends whatever data you provide, whether it is valid or not. The activity returns a status of Success if it was able to send the data, regardless of whether the data were correct or readable.

Address If you want to identify another computer as the agent that sends the SNMP trap information, type the agent address in the box. Otherwise, leave the box blank.
