To enable and configure global Cflowd sampling on an NE

Purpose

Cflowd collects statistical data based on traffic flows. A flow is a series of packets in a user session. Cflowd data is used to monitor network usage trends and detect security threats. You can use the NFM-P to configure Cflowd sampling for:

global traffic that passes through an NE; you must enable Cflowd globally on an NE before you can configure Cflowd collectors. You can create multiple Cflowd collectors on an NE. Each collector is deleted if Cflowd sampling is disabled.
traffic that passed through an ISA-AA group and/or partitions within the group as well as TCP performance data collection for AA applications and application groups; see To configure Cflowd collectors on an ISA-AA group or partition .
unicast and multicast traffic on a routing network interface, IES/VPRN L3 access interface, IES/VPRN tunnel interface, and VPRN network interface; see To create an L3 network interface on a routing instance , To configure a tunnel interface on an IES or VPRN , To configure an L3 access interface on an IES site , To configure an L3 access interface on a VPRN site , or To configure a network interface on a VPRN site .
traffic that passes through a group interface on an IES or VPRN; see To configure a group interface on an IES or To configure a group interface on a VPRN.
traffic that is redirected to Cflowd using an ACL IP or IPv6 filter policy; see To configure an ACL IP filter policy or To configure an ACL IPv6 filter policy.

You can create up to five Cflowd sampling rate profiles per system. Sampling rate profiles allow you to set different sampling rates on a per interface basis. This allows you to choose the appropriate sampling rate based on the services or type of traffic that is to be received or sent through the associated interface.

Steps


1	On the equipment tree, right-click on an NE and choose Properties. The Network Element (Edit) form opens.
2	Click on the CFLOWD tab.
3	Set the CFLOWD State parameter to Enabled.
4	Configure the required parameters in the CFLOWD Attributes panel.
5	Add a collector. Note: A global NE Cflowd configuration can contain up to eight collectors. Click on the Collector tab and click Create. The Cflowd Collector Configuration (Create) form opens. Configure the required parameters. The parameters vary based on the value of the Version parameter. Save your changes and close the form.
6	If you added a collector with the value of the Version parameter set to version 9 or 10, you can create filters that specify which flows are sent to a collector. Select a version 9 or 10 collector and click Create. The Cflowd Collector Configuration (New Instance) (Create) form opens. Click on the Export Filters and Interface List tabs and click Create. The Export Filter Interface List (Create) form opens. Configure the required parameters. Save your changes and close the form.
7	As required, create a Cflowd sampling rate profile. Click on the Sample Profile tab. The Cflowd Sample Profile (New Instance) form opens. Configure the parameters. Save your changes and close the form. Repeat these steps for up to five profiles.
8	Save your changes and close the form. End of steps
