Netflow Policy Configuration

About this task

Starting with the WiNG 7.3.0 release, 802.11ax APs will support Internet Protocol Flow Information eXport (IPFIX), an IEEE standard based on NetFlow version 9. 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 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 NetFlow Collector host and specifies the interval at which templates are exported to the specified NetFlow Collector.

Note

Note

NetFlow is only supported on the following 802.11ax APs: AP410i/e, AP460i/e, AP505i, AP510i/e, AP560i/h

To define a NetFlow Policy:

Procedure

  1. Navigate to Configuration → Network → Netflow Policy.
    The Netflow Policy screen displays.
    Click to expand in new window
  2. Review the existing NetFlow policy configurations to determine if a new policy warrants creation or an existing policy warrants deletion or modification.
    Name Lists the 32 character maximum name assigned to each listed Netflow Policy.
    Collector Address Lists the NetFlow Collector host's IPv4 address.
    Collector Port Lists the port at which the NetFlow Collector can be reached.
    Protocol Lists the protocol used to communicate with the Netflow Collector.
    Note: The current implementation only supports UDP protocol.
    Template Interval Lists the interval, in seconds, at which the AP (Exporter) exports NetFlow templates to the specified NetFlow Collector host.
  3. Select Add to create a new policy.
    To modify or delete an existing policy, select it and click Edit or Delete respectively. You can also Copy, Rename or Replace existing policies.
    The NetFlow Policy Add screen displays.
    Click to expand in new window
  4. If creating a new policy, assign it a Name not exceeding 32 characters in length.
  5. Define the following parameters to enable IP flow data forwarding to the NetFlow Collector:
    Collector Address Specify the NetFlow Collector host's IPv4 address or hostname
    Collector Port Specify the port on which the NetFlow Collector host is reachable. Set a value from 1 - 65,535.
    Note: The default port value is 2095.
    Protocol Specify the protocol type used to communicate with the NetFlow Collector host. The options are TCP and UDP.
    Note: The current implementation only supports UDP protocol. The default value is UDP.
    Interval Template Specify the interval, in seconds, at which the AP (Exporter) exports NetFlow templates to the specified NetFlow Collector host. Set a value from 300 - 3600 seconds.
    Note: The default value is 300 seconds.
  6. Select OK to save your changes.
    Click Reset to revert to the last saved configuration.

What to do next

Apply the Netflow policy locally on the AP or in the AP's profile context.
