2. From the Main Menu, select Security then Embedded
Authentication Server. The Embedded Authentication Server
screen appears.
3. Check Enable Server.
4. Select Submit Changes.
5. (Optional) In the Default Secret Key field, enter a default secret key
that is used between the EAS and all access points. This secret key can
be from 1 to 32 characters in ASCII or in hexadecimal. To enter a
hexadecimal key, it must start with 0x.
6. In the UDP Port field, enter the UDP port number on which the EAS
listens. Port number assignments are administered by the Internet

should choose a number between 49152 and 65535.
7. In the Authorization Time field, enter the amount of time that RADIUS
clients (access points) remain authorized by the server before they
need to be reauthorized. The format is d:hh:mm, where d is days, hh
is hours, and mm is minutes.
