Useful Information:
|
|
1. Polling interval for checking traffic is fixed at 1 minute
|
|
2. The test will exit when traffic has not changed on a station for 1 minute
|
|
3. The tx/rx rates are fixed at 256000 bits per second
|
|
4. Security is fixed at WPA2
|
|
5. Maximum stations per radio is 64

test_l3_longevity.py:
|
|
--------------------
|
|
Basic Idea: create stations, create traffic between upstream port and stations, run traffic.
|
|
The traffic on the stations will be checked once per minute to verify that traffic is transmitted
|
|
and recieved.
|
|
|
|
Test will exit on failure of not recieving traffice for one minute on any station.
|
|
|
|
Scripts are executed from: ./lanforge/py-scripts
|
|
|
|
Generic command layout:
|
|
python3 .\\test_l3_longevity.py --test_duration <duration> --endp_type <traffic type> --radio <radio 0> <stations> <ssid> <ssid password>
|
|
|
|
Note: multiple --radio switches may be entered up to the number of radios available:
|
|
--radio <radio 0> <stations> <ssid> <ssid password> --radio <radio 01> <stations> <ssid> <ssid password>
|
|
|
|
<duration>: number followed by one of the following
|
|
d - days
|
|
h - hours
|
|
m - minutes
|
|
s - seconds
|
|
|
|
<traffic type>:
|
|
lf_udp : IPv4 UDP traffic
|
|
lf_tcp : IPv4 TCP traffic
|
|
lf_udp6 : IPv6 UDP traffic
|
|
lf_tcp6 : IPv6 TCP traffic
|
|
|
|
Example:
|
|
1. Test duration 4 minutes
|
|
2. Traffic IPv4 TCP
|
|
3. Upstream-port eth1
|
|
4. Radio #1 wiphy0 has 32 stations, ssid = candelaTech-wpa2-x2048-4-1, ssid password = candelaTech-wpa2-x2048-4-1
|
|
5. Radio #2 wiphy1 has 64 stations, ssid = candelaTech-wpa2-x2048-5-3, ssid password = candelaTech-wpa2-x2048-5-3
|
|
|
|
Command:
|
|
python3 .\\test_l3_longevity.py --test_duration 4m --endp_type lf_tcp --upstream_port eth1 --radio wiphy0 32 candelaTech-wpa2-x2048-4-1 candelaTech-wpa2-x2048-4-1 --radio wiphy1 64 candelaTech-wpa2-x2048-5-3 candelaTech-wpa2-x2048-5-3
