Use the iPerf service
Your Connect IT 16/48 device includes an iPerf3 server that you can use to test the performance of
your network.
iPerf3 is a command-line tool that measures the maximum network throughput an interface can
handle. This is useful when diagnosing network speed issues, to determine, for example, whether a
cellular connection is providing expected throughput.
The Connect IT 16/48 implementation of iPerf3 supports testing with both TCP and UDP.
Note Using iPerf clients that are at a version earlier than iPerf3 to connect to the Connect IT 16/48
device's iPerf3 server may result in unpredictable results. As a result, Digi recommends using an iPerf
client at version 3 or newer to connect to the Connect IT 16/48 device's iPerf3 server.
Required configuration items
n Enable the iPerf server on the Connect IT 16/48 device.
n An iPerf3 client installed on a remote host. iPerf3 software can be downloaded at
https://iperf.fr/iperf-download.php.
Additional configuration Items
n The port that the Connect IT 16/48 device's iPerf server will use to listen for incoming
connections.
n The access control list for the iPerf server.
When the iPerf server is enabled, the Connect IT 16/48 device will automatically configure its
firewall rules to allow incoming connections on the configured listening port. You can restrict
access by configuring the access control list for the iPerf server.
