protocol is used, and data is protected during the configuration session. When it is turned off, the HTTP protocol is used, and data could be intercepted during the configuration session. Changing this option causes the device to reset, which disrupts the network association temporarily, but does not affect device configuration settings that have already been saved. When the Secure Web Server Connection is On, you must specify "https://" in the browser window address pane when launching the configuration. RADIUS The RADIUS page lets you define the servers to be used for authentication. RADIUS (Remote Authentication Dial-in User Service) is a logon authentication protocol that uses software running on a central server to control access to RADIUS-compliant devices on the network. It allows an access point to send the connection parameters to a RADIUS server. Enter the required parameters for a primary and secondary RADIUS server. Configuring a secondary RADIUS server provides a backup in case the primary server fails. The access point will use the secondary server if a failure is detected in the primary server. Once the access point switches over to the secondary server, it periodically attempts to establish communication again with primary server. Once communication is established, the secondary server reverts back to a backup server. The parameters are described below. When you are finished configuring items on this page, click Apply. I IP Address-The address of the authentication server. I Port-The network (UDP) port of the authentication server used for authentication messages. The port defaults to 1812 and must match the port configured on the RADIUS server. I Key-The encryption key a shared ASCII string that is used to authenticate logon access for the client. The maximum length is 255 characters. Do not use blank spaces in the string. The key must be configured the same on both the access point and the RADIUS server. I Timeout-The number of seconds the access point waits for a reply from the RADIUS server before it resends the request. I Retransmit attempts-The number of times the access point will try to authenticate logon access via the authentication server. 29

RADIUS
The RADIUS page lets you define the servers to be used for authentication.
RADIUS (Remote Authentication Dial-in User Service) is a logon authentication
protocol that uses software running on a central server to control access to
RADIUS-compliant devices on the network. It allows an access point to send the
connection parameters to a RADIUS server. Enter the required parameters for a
primary and secondary RADIUS server.
Configuring a secondary RADIUS server provides a backup in case the primary
server fails.
The access point will use the secondary server if a failure is detected
in the primary server.
Once the access point switches over to the secondary
server, it periodically attempts to establish communication again with primary
server.
Once communication is established, the secondary server reverts back to a
backup server.
The parameters are described below. When you are finished configuring items on
this page, click

■
IP Address
—The address of the authentication server.
■
Port
—The network (UDP) port of the authentication server used for
authentication messages. The port defaults to 1812 and must match the port
configured on the RADIUS server.
■
Key
—The encryption key a shared ASCII string that is used to authenticate
logon access for the client. The maximum length is 255 characters. Do not use
blank spaces in the string. The key must be configured the same on both the
access point and the RADIUS server.
■
Timeout
—The number of seconds the access point waits for a reply from the
RADIUS server before it resends the request.
■
Retransmit attempts
—The number of times the access point will try to
authenticate logon access via the authentication server.
