The error message "5405 RADIUS Request dropped", what does it meen ?.
We have implemented 802.1X on a C4506 switch running IOS 12.2(53), it has worked fine for about 3 months but now I get users not able to authenticate. In the loggs on the ACS I get the obove message.
ACS 5.2 is running 5.2.0.26 Build 3075.
Has anyone have hade the same problem ?

Have you resolved the problem?
I started facing this problem when I played around with the dot1x timeout parameters. I have seen that making these too small causes this problem. I am looking into these but if you share your experience it might help.

It's fixed in 5.3...
...or stop/start ACS as a workaround till it's happen again.
Kind regards,
