How to configure NetFlow on ADTRAN NetVanta routers

NetFlow v9 is supported on ADTRAN AOS firmware version 17.2.1 or higher.

These instructions assume:

• The date, time and time zone are correctly set on the router.
• You have Telnet or SSH credentials and access to your ADTRAN NetVanta router.
• The IP address of your Auvik collector is known.

If you are using a shared collector and want TrafficInsights to associate flow data with the correct site, you must add the source IP address as a dedicated /32 network within Auvik.

For example:

192.168.1.10/32

Even if the source IP address is already included in a larger monitored subnet, a dedicated /32 entry is required for TrafficInsights to correctly associate flow records with the appropriate site.

After making this change, it may take several minutes before flow data appears in TrafficInsights.

Access your router CLI

1. Telnet or SSH into your router.
2. Enter privileged mode by typing enable and entering your enable password.

Enable netflow

1. On your router, execute the following command. Replace AuvikCollectorIP with the IP of your Auvik collector and AuvikPort with one of the following ports: 2055, 2056, 4432, 4739, 6343, 9995, or 9996.

   interface ethernet 0/1
   ip ffe
   ip flow ingress auvik
   ip flow export destination <AuvikCollectorIP> <AuvikPort>
   ip flow cache timeout active 60
   ip flow export template timeout-rate 180
   ip flow cache sample one-out-of 1 random
   
   Exit

2. Run the following command to confirm the configuration: show ip flow
3. Exit configuration mode and save changes.
4. Save the current running configuration to the startup configuration file: copy running-config startup-config
