Setup Tasks
To set up TFA, you will need to configure one or more devices to send traffic flow data to
OpenManage Network Manager and you will also need to register these devices as exporters. Each
of these tasks begins from the Managed Resources portlet and the Traffic Flow Analyzer sub-menu
that appears when you right-click on a device.
Creating TFA Configuration for a Managed Resource (Top-Level
Device)
For any devices in which you would like to get visibility into what traffic is flowing through it, you
will need to configure such devices to summarize and/or to sample this data and to send the flow
information to OpenManage Network Manager. This can be done automatically for some device
vendors and models by using the Create Configuration menu item. Note that not all devices and
models are supported, and thus manual configuration would be necessary for unsupported models.
Manual configuration can often be accomplished by logging into the device either through CLI
commands and/or through a web GUI. Please check the documentation for your device to see if
any traffic flow protocols are supported, and if so how to enable this feature. For automatic
configuration, follow these steps::Setup
1 From the Managed Resources portlet, right-click on the appropriate device.
2 Select Traffic Flow Analyzer >Create Configuration.
3 popup box will appear that prompts for the parameters that are necessary to perform this
action. These parameters are determined by the configuration parameters of the device
model. Depending on the device model, these parameters might include sample rate, active
timeout, etc.
4 After you have entered the appropriate parameters, click Execute.
5 If this operation was successful then the device should be configured to send traffic flows to
{product name} using one of the supported protocols (sFlow, NetFlow, IPFIX). Please note,
however, that for some models it is also necessary for you to create configuration for TFA at
both the device level (using the Managed Resources portlet) and also at the subcomponent
level (using either the Ports or Interfaces portlet, which is described in the next section.
Creating TFA Configuration for a Port or Interface (Subcomponent)
Depending on the device model, you might need to create the TFA configuration for both the top-
level device and for one or more of its subcomponents (ports and interfaces). You will probably
have to first configure the top-level device and then you can configure the subcomponent. To
create TFA configuration for a subcomponent, follow these steps:
1 From either the Ports or Interfaces portlet, right-click on the appropriate device.
2 Select Traffic Flow Analyzer >Create Configuration.
3 A popup box will appear that prompts for the parameters that are necessary to perform this
action. These parameters are determined by the configuration parameters of the device
model. Depending on the device model, these parameters might include polling interval,
sample rate, etc.
4 After you have entered the appropriate parameters, click Execute.
