The pass key can be any alphanumeric string. The switch, other proprietary routers and
Brocade MUs use the algorithm to convert an ASCII string to the same hexadecimal number.
MUs without Brocade adapters need to use WEP keys manually configured as hexadecimal
numbers.
6. Use the Key #1-4 areas to specify key numbers.
The key can be either a hexadecimal or ASCII. For WEP 64 (40-bit key), the keys are 10
hexadecimal characters in length or 5 ASCII characters. Select one of these keys for activation
by clicking its radio button.
Default (hexadecimal) keys for WEP 64 include:
7. If you feel it necessary to restore the WEP algorithm back to its default settings, click the
Restore Default WEP Keys button. This may be the case if you feel the latest defined WEP
algorithm has been compromised and longer provides its former measure of data security.
8. Refer to the Status field for the current state of the requests made from applet. This field
displays error messages if something goes wrong in the transaction between the applet and
the switch.
9. Click OK to use the changes to the running configuration and close the dialog.
10. Click Cancel to close the dialog without committing updates to the running configuration.
Configuring WEP 128 / KeyGuard
WEP 128 provides a more robust encryption algorithm that WEP 64 by requiring a longer key length
and pass key. Thus, making it harder to hack through the replication of WEP keys. WEP 128 may be
all that a small-business user needs for the simple encryption of wireless data.
KeyGuard is an enhancement to WEP encryption, and was developed before the finalization of
WPA-TKIP. This encryption implementation is based on the IEEE Wireless Fidelity (Wi-Fi) standard,
802.11i.
To configure WEP 128 or KeyGuard:
1. Select Network > Wireless LANs from the main menu tree.
2. Select an existing WLAN from those displayed within the Configuration tab and click the Edit
button.
A WLAN screen displays with the WLAN’s existing configuration. Refer to the Authentication
and Encryption columns to assess the WLAN’s existing security configuration.
3. Select either the WEP 128 or KeyGuard button from within the Encryption field.
4. Click the Config button to the right of the WEP 128 and KeyGuard checkboxes.
The WEP 128 / KeyGuard screen displays.
