New Supplicant Auth Fail. is displayed, authentication failed
for either of the following reasons. Check for problems.
The user ID or password has not been registered on the

displayed, authentication failed because the maximum number of
supplicants for the device was exceeded.

The number of supplicants on the interface is full is
displayed, authentication failed because the maximum number of
supplicants for the interface was exceeded.
• If
Failed to authenticate the supplicant because it
