Overview

This topic describes how to perform network throughput tests between Controller Nodes using a tool named iperf. Iperf  is a tool for performing network throughput measurements. It can test either TCP or UDP throughput. To perform an iperf test, the user must establish both a server (to discard traffic) and a client (to generate traffic). For more information on iperf, such as options and environment information, refer to the Iperf - Perform Network Throughput Tests topic.
 

The example procedure in this topic describes how to test the network speed between two Lattus Controller Nodes.

 

The following command is used on the receiving Controller Node (Server):

 

• # iperf -s

Then the following command is used on thesending Controller Node (Client):

 

• # iperf -c <receiving IP address> -t 60
   

---

Procedure

1.  Launch the server on Controller Node 1 (Controller1):

# iperf -s

 

 

2. Start the client from Controller Node 3 (Controller3):

# iperf -c <receiving IP address> -t 60

 

 

3. View the results on both Controller Nodes: 

Controller1:

 

 

 

Controller3:
