Table 6-1 RADIUS
Enter the port number that the RADIUS server uses for accounting. You only need
to change this value from the default if your network administrator gave you a
specific port number to use. The allowed numbers are from 0 to 65535.
Enter a password (up to 64 characters) as the key to be shared between the
RADIUS server and the ZyAIR. The key is not sent over the network. This key must
be the same on the RADIUS server and the ZyAIR.
At times the ZyAIR may not be able to use the primary RADIUS server. Select the
number of times the ZyAIR should reattempt to use the primary RADIUS server
before attempting to use the secondary RADIUS server. This also sets how many
times the ZyAIR will attempt to use the secondary RADIUS server.
For example, you set this field to 3. If the ZyAIR does not get a response from the
primary RADIUS server, it tries again up to three times. If there is no response, the
ZyAIR tries the secondary RADIUS server up to three times.
If there is also no response from the secondary RADIUS server, the ZyAIR stops
attempting to authenticate the subscriber. The subscriber will see a message that
says the RADIUS server was not found.
Select Disable if you will not use an external RADIUS server to perform accounting
for the wireless client accounts.
Select Enable to use an external RADIUS server to perform accounting for the
wireless client accounts.
Specify the time interval for how often the ZyAIR is to send a subscriber status
update to the RADIUS server.
Enter the authentication protocol that the RADIUS server uses.
PAP (Password Authentication Protocol) requires users to enter a password before
accessing a secure system. The user's name and password are sent over the wire
to a server where they are compared with a database of user account names and
passwords.
CHAP (Challenge Handshake Authentication Protocol) avoids sending passwords
over the wire by using a challenge/response technique.
The iPass company provides connectivity services for mobile Internet users. Select
this check box to have the ZyAIR use the iPass Generic Interface Specification
(GIS) method to authenticate iPass clients. Your external RADIUS servers must be
Wi-Fi based Wireless Internet Service Provider roaming (WISPr) compliant in order
to authenticate iPass clients.
When using iPass GIS, your ISP will provide you with login mode information.
Select Directly Reply, Proxy Reply with "Redirect Login Page" URL or Proxy
Reply with Specific URL (and enter the URL in the field provided). The login mode
information for the iPass GIS connection. (Provided by your ISP).
