In this article,i will share with you troubleshootin roadmap for STA Failures from Huawei Tech Support
1-) Smart-Roaming function could effect STA devices to disassociate from WIFI
2-) If there is inter-ac roaming we should add our roaming ap in WIDS Whitelist
3-) Check whether STA or AP is under attack or not ? (Configure Attack Detection Function and display wids attack statistics) and force rogue devices disassociation under dynamic black-list
4-) Check if sta goes offline due to Roamin Failure
5-) Check whether problem caused by radio interference existence or not
If you can't find certain reason after you investigate the upper instructions as per article
You can run the below commands in order to analyze Root Cause of STA Failure.
display aaa abnormal-offline-record mac-address xxxx-xxxx-xxxx = (this command display abnormal logouts on device)
display aaa online-fail-record mac-address xxxx-xxxx-xxxx = (this command display login failure records )
display aaa offline-record mac-address xxxx-xxxx-xxxx = (this command display normal logouts records)
display station offline-record sta-mac/ap-id = (displays STAs' going-offline records.)
