Configuring Flow Exports on Arista switches

For network traffic analysis, you need to configure your devices to export flows to Site24x7 On-Premise Poller, which is the sFlow collector. The On-Premise Poller will be listening to a particular port to receive flows. Learn how to find the port number of your On-Premise Poller.

To enable sFlow in Arista switches:

1. Connect to the Arista switch by using SSH or Telnet.
2. To enter enable or privilege mode, type enable and provide the appropriate password if needed.
3. To enable sFlow on your Arista switch, including all the interfaces, execute the below commands in sequence: 
   
   copied

   sflow run
   sflow destination  {NetFlow server IP address}
   sflow source {IP address}
   sflow polling-interval 60
   sflow sample {Sample rate}

   

   Packet sampling occurs at regular intervals (denoted by Sample rate in the above command) to prevent inaccurate sampling. For example, a sample rate of 12,345 indicates one sample is taken for every 12,345 packets. The default value is 1,048,576.
4. To verify the sFlow configuration, execute the below commands on the device terminal:
   
   copied

   show sflow
   show sflow interfaces
