The WifiPerf feature in cnPilot APs (E series and R series devices) enables them to measure network performance, which helps to identify/resolve network issues. Performance test, will be executed between cnPilot AP and another WifiPerf endpoint as per below scenarios.
Endpoints are a pair of network elements between which Network performance is measured. In our case one endpoint is a cnPilot AP, while the other could be cnMaestro On-Premises instance or another cnPilot AP, or any host PC running “zapwireless” application .(Wifiperf Interoperate with open source zapwireless tool https://code.google.com/archive/p/zapwireless/.)
A Wifiperf manager is a network element from which the Wifiperf test can be initiated. This could be a cnMaestro On-Premises instance or a PC running “zapwireless” application.
The Wifiperf manager establishes control session with wifiperf endpoints using TCP port number 18301. So it is mandatory that wifiperf endpoints are reachable from wifiperf manager. Make sure the NAT/firewall does not block the traffic from wifiperf manager to any endpoint and between the endpoints. Also, ensure that port number 18301 is not blocked in the network for TCP and UDP.
Executing WifiPerf using cnMaestro On- Premises
This is applicable for both E-series and R-series devices. APs should be on-boarded into cnMaestro.As mentioned earlier, make sure Wifiperf traffic (TCP/UDP traffic with port number 18301) is allowed from cnMaestro to cnPilot AP. (no NAT or firewall barrier).
To run the Wi-Fi performance test, navigate to Tools > Wi-Fi Performance page.
Duration can be selected as 10, 20, 30 seconds, and traffic type/protocol select as UDP or TCP.
WifiPerf manager running on cnMaestro on-premises initiate the test between AP and selected WifiPerf endpoint and output will be displayed.
Uplink direction is cnPilot AP to other wifiperf endpoint and Downlink is other wifiperf end point to cnPilot AP.
Common scenarios of wifiperf test from cnMaestro On-premises are explained below and you need to select the end point as per the scenarios.
Wifiperf test between cnMaestro On-Premises and cnPilot AP
cnMaestro On-Premises is having a built-in wifiperf manager and wifiperf endpoint. Test will be performed between AP and cnMaestro on-Premises.
Prior to start the test , make sure wifiperf is enabled on cnMaestro on-premises. To enable wifiperf service on cnMaestro by Navigate to Application ->settings and enable wifiperf Daemon
To perform the test select end point as cnMaestro.
Wifiperf test between a cnPilot AP and a local host
You can select local host (or any other cnPilot AP with wifiperf enabled) as endpoint in order to run speed test between AP and local host.
In order to setup the host computer as a wifiperf endpoint, install zap wireless tool in the local host.(https://code.google.com/archive/p/zapwireless/ )
Additionally, we also need to specify the IP address of this host in cnMaestro as shown below.
Navigate to network -> site -> configuration -> WiFiPerf Server
To perform the test with local host , select end point as local host.
Wifiperf test with a mesh Client
Wifiperf test for mesh client is only applicable only for E-series. Mesh client should be either cnPilot AP or any device with zap wireless running.
Other endpoint can be selected as cnPilot AP, cnMaestro or local host.
To perform the test for mesh client, navigate to mesh peers -> wifiperf test icon (highlighted with red below). Down link direction is Endpoint to mesh client and uplink is mesh client to endpoint.
This is supported only for E-series devices
This procedure is applicable for any of the below cases
Install zap wireless tool on local host PC and execute zapwireless test from host PC. (‘zap –s<DEVICE IP> -d <PC IP> - X<iteration>).

Prior to start the test , you need enable WifiPerf on cnPilot AP from device GUI ->navigate to configuration -> services - >Enable wifiperf
