802.1X auth failure
major, minor,
information
all controller
models
Radius server authentication failed. To
find out why, look at the Radius server log
for the error message and also check the
station log. If this happens only
occasionally, you can ignore it. However,
if this message appears repeatedly, the
authentication failures could prevent a
station from entering the network. In this
case, check the Radius server to make
sure the client and server have the same
credentials.
