Perform a speedtest

To perform a speedtest:

 Command line

Select the device in Remote Manager and click Actions > Open Console, or log into the IX10 local command line as a user with full Admin access rights.
Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

Use the iperf command to generate the report:

> iperf host

where host is the hostname or IP address of a speedtest host. For example:

> iperf speedtest.accns.com
Tx (upload) average: 50.1110 Mbps
Tx latency: 31.45 ms
Rx (download) average: 44.7588 Mbps
Rx latency: 30.05 ms
>

To output the result in json format, use the output parameter:

> iperf host output json
{"tx_avg": "51.8510", "tx_avg_units": "Mbps", "tx_latency": "31.07", 
"tx_latency_units": "ms", "rx_avg": "39.5770", "rx_avg_units": "Mbps", 
"rx_latency": "34.19", "rx_latency_units": "ms" }
>

To change the size of the speedtest packet, use the size parameter:
```
> iperf host size int
```
By default, the speedtest uses nuttcp for the mode. To change this setting from nuttcp to iperf, use the mode parameter:
```
> iperf host mode iperf
```
Type exit to exit the Admin CLI.
Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.
