NetFlow is a Cisco-proprietary protocol that collects IP flow data and exports it to a NetFlow Collector. IP flow data provides a highly granular insight of the network and facilitates fine-grained metering for highly flexible and detailed resource usage accounting.
IP flow data is exported by the APs to the NetFlow Collector using templates that contain supporting data record fields.
To enable IP flow data collection and export within your WiNG 7.3.0 managed network, create a NetFlow policy and apply locally on the AP or in the AP's profile context. The NetFlow policy identifies the Collector host and specifies the interval at which templates are exported to the specified Collector.
Note
NetFlow is supported only on the new 802.11ax APs. The NetFlow policy can be configured on the controller (NX5500, NX7500, NX9500, NX9600) and pushed to the AP. Or, you can configure the policy locally on the AP and use it in the AP's device or profile context.netflow-policy <NETFLOW-POLICY-NAME>
netflow-policy <NETFLOW-POLICY-NAME>
<NETFLOW-POLICY-NAME> | Specify the NetFlow policy name. If a policy with the specified name does not already exist, it is created. |

Apply the NetFlow policy to the AP's profile.

Or, apply the NetFlow policy locally on the AP:
