Configuring a WLAN
c. In the Accounting Shared Secret field, enter a string up to 127 characters
long. (The string can include alphanumeric and special characters.)
The accounting server uses the shared secret to verify that reports are from
a legitimate source. The key you specify must match the key configured for
the module in the accounting server’s client configurations.
If you are using the module’s internal server, you don’t need to specify a key.
6. Optionally, configure settings for a secondary server by completing the fields in
the Secondary column of the Accounting section.
7. Optionally, alter the value in the Accounting Timeout field.
This setting determines the length of time in seconds that the Wireless Edge
Services zl Module waits for an acknowledgement from the accounting server.
The default is five seconds, and the valid range is from 1 to 300 seconds. Raise
the timeout if your network or accounting server is frequently busy.
8. Optionally, alter the value in the Accounting Retries field.
If the module does not receive an acknowledgement from the accounting server,
it resends the report. The default number of retries is 6, and the valid range is
from 1 to 100.
Re-sending reports ensures that users’ activity is logged correctly—particularly
important if your company charges for wireless service.
9. From the Accounting Mode drop-down menu, choose when the Wireless Edge
Services zl Module sends a report:
• Start-Stop—when a station connects to this WLAN and when it disconnects
• Stop-Only—only when a station disconnects
• Start-Interim-Stop—when a station connects to this WLAN, periodically
for as long as the connection persists, and when the station closes the
connection
10. If you have selected Start-Interim-Stop for the Accounting Mode, enter a value
in the Interval field.
This setting determines how often, in seconds, the module sends periodic reports
on user activities. (It applies only when you select Start-Interim-Stop.) The
default value is 60 seconds, and the valid range is from 60 to 3600 seconds (1
hour).
11. Click the OK button.
12. In the WLAN’s Edit screen, click the OK button.
13. Click the Save link at the top of the Web browser interface to save the changes
to the startup-config.
