+= Configuring monitoring for SR-IOV interface traffic
+In order to collect traffic from a cluster with a Single Root I/O Virtualization (SR-IOV) device, you must set the `FlowCollector` `spec.agent.ebpf.privileged` field to `true`. Then, the eBPF agent monitors other network namespaces in addition to the host network namespaces, which are monitored by default. When a pod with a virtual functions (VF) interface is created, a new network namespace is created. With `SRIOVNetwork` policy `IPAM` configurations specified, the VF interface is migrated from the host network namespace to the pod network namespace.
+
+.Prerequisites
+* Access to an {product-title} cluster with a SR-IOV device. 
+* The `SRIOVNetwork` custom resource (CR) `spec.ipam` configuration must be set with an IP address from the range that the interface lists or from other plugins.
+
+.Procedure
+. In the web console, navigate to *Operators* -> *Installed Operators*.
+. Under the *Provided APIs* heading for the *NetObserv Operator*, select *Flow Collector*. 
+. Select *cluster* and then select the *YAML* tab.
+. Configure the `FlowCollector` custom resource. A sample configuration is as follows:

 The Loki Operator supports a few log storage options, such as AWS S3, Google Cloud Storage, Azure, Swift, Minio, OpenShift Data Foundation. The following example shows how to create a secret for AWS S3 storage. The secret created in this example, `loki-s3`, is referenced in "Creating a LokiStack resource". You can create this secret in the web console or CLI.
 
 . Using the web console, navigate to the *Project* -> *All Projects* dropdown and select *Create Project*. Name the project `netobserv` and click *Create*.
