Designing an Snmp network application

There are two types of Snmp applications, both of which are represented as NiagaraAX “devices”. Depending on how you plan to use the Niagara Snmp integration, you need to set up at least one or possibly both of these applications. Use the appropriate procedure or procedures to design the Snmp network, as described below:

Snmp Local Device (Agent)

Set up and use this NiagaraAX device for creating a “virtual” Snmp agent that can expose data from outside Niagara to Snmp Managers. Every SnmpNetwork has a local device and only one SnmpAgent object may be added to an SnmpNetwork.
Snmp Manager

Set up and use this NiagaraAX device for creating a “client” type application that you use to manage one or more Snmp Agent devices on your network. Under the Snmp Manager, SnmpDevice objects represent remote SnmpAgent devices that are configured to expose data from an actual Snmp device. You can add many SnmpDevice objects under your SnmpNetwork.

To set up an Snmp local device (agent application)

When you add an SnmpNetwork object, as described in To add an SnmpNetwork to the station, a Local Device component comes with it.

To set up an Snmp local device, do the following:

Right-click on the SnmpNetwork node and select Views->Property Sheet to display the SnmpNetwork property sheet in the view pane.
The Enabled property should be set to True. If not, select True from the option list.
Set the Snmp Receive Requests property to Enabled (can send traps). This allows the local device to receive outside request messages from external SNMP sources and to send trap messages.
Click the property sheet Save button.

You are now ready to add Snmp Agent Points under the local device in order to expose Niagara data to SNMP requests from outside sources.

Refer to Create Snmp proxy points for details about adding Snmp Agent Points.

To set up an Snmp manager application

For SNMP manager applications, you add SnmpDevice objects to your SnmpNetwork to represent actual SNMP agent devices that you want to manage.

To set up an Snmp manager application, do the following:

Under the Drivers node of your station, double click on the SnmpNetwork node in the nav side bar. The Snmp Device manager view displays.
Using the palette side bar controls, open the local SNMP module palette, expand the Client folder and copy-and-paste (or drag and drop) an SnmpDevice object into the view pane. The Name dialog box appears.
Name the SnmpDevice, as desired and click the OK button. The device is added to the Snmp Device Manager view and represents one SNMP agent device on your network. You can add more of these objects, if needed, each representing a single SNMP agent device under your Snmp manager application.
Double click on the added device in the Snmp Device Manager view. The Edit dialog appears.
In the Edit dialog box, set the Snmp Version and Ip Address (actual device Ip address) fields, then click the OK button. The SnmpDevice is added under the SnmpNetwork. Refer to SNMP device configuration for more complete Snmp device configuration information.
