Wireless Local Area Networks (WLANs)
Configuring a WLAN
9. In the MAC Address section, choose the format in which the Wireless Edge
Services zl Module forwards the MAC address.
The module sends the station’s MAC address as the username and the password
in the RADIUS request. The username and password must match exactly those
in the account against which the RADIUS server checks them. For example, if
the account uses delimiters in the MAC address, the module must use delimiters
in the same places.
Choose from among five options for the format:
• No Delimiter (xxxxxxxxxxxx)
• Multi Colon (xx:xx:xx:xx:xx:xx)
• Multi Dash (xx-xx-xx-xx-xx-xx)
• Quad Dot (xxxx.xxxx.xxxx)
• Single Dash (xxxxxx-xxxxxx)
10. Click the OK button.
11. If you want to use encryption, you should now configure the encryption option.
See “Configuring Encryption” on page 4-46.
Configuring Encryption
Encryption ensures the privacy of data sent through the wireless medium. Even if
hackers intercept packets, they cannot decrypt them without the correct key.
The WLANs controlled by the Wireless Edge Services zl Module can support any of
these encryption standards, listed from least secure to most secure:
■ Wired Equivalent Privacy (WEP) with a 64-bit
■ WEP with a 128-bit key
■ Wi-Fi Protected Access (WPA)/WPA2 with Temporal Key Integrity Protocol
(TKIP)
■ WPA2 with Advanced Encryption Standard (AES)
No matter which type of authentication you select, you can select any type of
encryption. You can select both WPA/WPA2-TKIP and WPA2-AES at the same time.
However, all other encryption options are mutually exclusive.
If your WLAN does not use authentication, the encryption option enforces a de facto
authentication: the user must enter the correct encryption key in order to connect to
the WLAN. However, this form of authentication is less secure, particularly when
used with WEP.
Table 4-2 displays the names that this management and configuration guide uses for
combinations of authentication and encryption options.
