802.1x Authentication
If you enable the 802.1x authentication function, you will have to offer the following information-
RADIUS Server: RADIUS Server is a protocol for carrying authentication, authorization, and
configuration information between a Network Access Server which desires to authenticate its links
and a shared Authentication Server. Please key in the IP Address for the RADIUS Server.
RADIUS Port: Besides the IP address of the RADIUS Server, you have to enter the port number for
the server. Port 1812 is the reserved RADIUS-authentication port described in RFC 2138. Earlier AP
(RADIUS clients) use port 1945. The default value will be shown on this box. You can keep and use
it.
RADIUS Key: A RADIUS Key is like a password, which is used between IAS and the specific
RADIUS client to verify identity. Both IAS and the RADIUS client must be use the same RADIUS
Key for successful communication to occur. Enter the RADIUS Key.
WPA/WPA2
For the WPA/WPA2 network Authentication, the settings that you can adjust including WPA/WPA2
Encryption, RADIUS Server, RADIUS Port, RADIUS Key, Group Key Rotation Interval, and
WPA/WPA2 Re-auth Interval.
WPA/WPA2 Encryption: There are three types that you can choose, TKIP*, AES**, TKIP+AES.
TKIP takes the original master key only as a starting point and derives its encryption keys
mathematically from this mater key. Then it regularly changes and rotates the encryption keys
so that the same encryption key will never be used twice
** AES provides security between client workstations operating in ad hoc mode. It uses a
mathematical ciphering algorithm that employs variable key sizes of 128, 192 or 256 bits.
RADIUS Server/RADIUS Port/RADIUS Key: Please refer to the previous page.
