NAME: lf_wifi_mobility_test.py
PURPOSE: The Candela Roam test uses the forced roam method to create and roam hundreds of WiFi stations between two
or more APs with the same SSID on the same channel or different channels. The user can run thousands of roams over
long durations and the test measures roaming delay for each roam, station connection times, network down time,
packet loss etc.. The user can run this test using different security methods and compare the roaming performance.
The expected behavior is the roaming delay should be 50msecs or less for all various kinds of fast roaming methods to
avoid any form of service interruption to real-time delay sensitive applications
EXAMPLE:
example 1:
python3 lf_wifi_mobility.py --mgr 192.168.200.96 --port 8080 --lf_user lanforge --lf_password lanforge
--bssid_list "90:3c:b3:9d:69:3e,34:EF:B6:AF:49:08" --stations "1.1.sta0000"
--pull_report == If specified, this will pull reports from lanforge to your code directory,
from where you are running this code
Suggested: To have a scenario already built.
