Configuring a WLAN
8. In the Radius Configuration screen, under Server, specify settings for your
network’s RADIUS servers.
Enter settings for your primary server in the fields in the Primary column:
a. In the RADIUS Server Address field, specify the IP address of your
network’s primary RADIUS server.
To use the module’s internal server, enter 127.0.0.1.
b. Leave the RADIUS Port field at the default value unless you know that
your server uses a different port.
The default value is 1812.
c. In the RADIUS Shared Secret field, enter a character string up to 127
characters.
The RADIUS server uses the secret to identify the Wireless Edge
Services xl Module as a legitimate client. You must match the secret
configured for the module in your RADIUS server’s configuration.
If you are using the module’s internal server, you do not need to enter
a shared secret.
d. Optionally, enter settings for a secondary RADIUS server in the fields
in the Secondary column.
9. Optionally, alter other RADIUS server settings:
• Enter a value in the Server Timeout to control how long the Wireless
Edge Services xl Module will wait for a reply from the RADIUS server.
The Server Timeout can be from 1 to 60 seconds, and the default setting
is 5 seconds.
• Enter a value in the Server Retries fields to control how many times
the module will reattempt to contact a server that does not reply.
The setting for Server Retries can be from 1 to 10. By default, the value
is 3; Wireless Edge Services xl Module attempts to contact the server
up to four times (one initial try and three subsequent tries).
10. Check the Re-authentication box if you want to force stations to periodi-
cally re-authenticate to the network. Specify how often (in seconds)
stations must re-authenticate in the Re-authentication Period field.
Re-authentication occurs in the background. By default, re-authentication
is disabled, but if you enable it, the default period is one hour (3600
seconds). The valid range is 30 to 65535 seconds.
11. Choose the protocol in which the Wireless Edge Services xl Module
packages users’ credentials. Select PAP (the default) or CHAP for the
Authentication Protocol.
