Configuring a WLAN
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
zl 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.
7. Check the Re-authentication box if you want to force stations to periodically 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.
8. Optionally, alter settings in the Advanced section:
• Enter a value in the Server Timeout to control how long the Wireless Edge
Services zl 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 Wireless
Edge Services zl Module attempts to contact the server up to four times (one
initial try and three subsequent tries).
9. Optionally, enter a value in the DSCP/TOS field to prioritize traffic to the
RADIUS server.
Valid values range from 0 through 63.
a. Leave the other settings at their defaults and click the OK button. You will
return to the WLAN’s Edit screen.
10. You must now configure the encryption option. See “Configuring Encryption”
on page 4-46.
