|
Create connections using stations with different a/b/g/n/AC/AX modes,
|
|
traffic with different QoS, packet size, requested rate, and tcp or udp protocol.
|
|
Report the latency and other throughput values.
|
|
|
|
make sure pexpect is installed:
|
|
$ sudo yum install python3-pexpect
|
|
$ sudo yum install python3-xlsxwriter
|
|
|
|
You might need to install pexpect-serial using pip:
|
|
$ pip3 install pexpect-serial
|
|
$ pip3 install XlsxWriter
|
|
|
|
When specifying ports, if the port starts with [Number]., like 1.eth1, then the 1 specifies
|
|
the resource ID.
|
|
|
|
The --cx argument is defined as: station-radio, station-port, mode, upstream-port, protocol, pkt-size, speed_ul, speed_dl, QoS.
|
|
Pass this argument multiple times to create multiple connections.
|
|
|
|
Supported modes are: a, b, g, abg, abgn, bgn, bg, abgnAC, anAC, an, bgnAC, abgnAX, bgnAX, anAX
|
