Configuring Flow Exports on F5 Load Balancer
For NetFlow analysis, you need to configure your devices to export flows to Site24x7 On-Premise Poller, which is the NetFlow collector. The On-Premise Poller will be listening to the particular port to receive flows. Learn how to find the port number of your On-Premise Poller.
Configure F5 load balancers to export sFlow using the web interface by following the steps below:
- Log in to your F5 load balancer.
- From to the Main tab, go to System > sFlow > Receiver List.
- In the sFlow screen that opens, click Add.
- In the New Receiver properties screen that opens, enter the following:
- Name: Enter a name for the sFlow receiver.
- Address: Enter the IPv4 or IPv6 address on which the sFlow receiver listens for UDP datagrams.
NoteThe IP address of the sFlow receiver must be reachable from a self IP address on the BIG-IP system.
- From the State list, select Enabled.
- Click Finished.
Setting the sFlow polling interval for an interface
You can configure the sFlow polling interval for a specific interface, only if you are assigned either the Resource Administrator or Administrator user roles.
- From the Main tab, click Network > Interfaces > Interface List.
- From the Interface list, in the Name column, click an interface number.
- This displays the properties of the interface. From the Polling Interval list, select Specify, and type the maximum interval in seconds between polling by the sFlow agent of this interface.
- Click the Update button.
