TitleWith netlogin dot1x Radius retries do not seem to work
Symptoms
Clients fail 802.1X authentication - mostly when attached to switches at remote locations with the Radius server at HQ over WAN links.
Environment
Platform: SummitX
Firmware versions: 16.1.3.x, 21.1.1.4
 
Cause
If the WAN/DSL links between a remote site and HQ are poor or congested Radius packets may be dropped. If the authentication attempted is 802.1X the retries will not be sent by the authenticator as per the default/configured timers - they will only initiate after 2 min - by that time the authentication session went stale.
 
Resolution
A fix was produced and added to the following EXOS firmware versions at the time when this article was published:
16.1.4.x
16.2.2.x
22.2.1.x
