Configuring WEP 64
Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE Wireless Fidelity (Wi-Fi)
standard. WEP is designed to provide a WLAN with a level of security and privacy comparable to
that of a wired LAN.
WEP 64 is a less robust encryption scheme than WEP 128 (shorter WEP algorithm for a hacker to
duplicate), but WEP 64 may be all that a small-business user needs for the simple encryption of
wireless data. However, networks that require more security are at risk from a WEP flaw. The
existing 802.11 standard alone offers administrators no effective method to update keys.
To configure WEP 64:
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
3. Select the WEP 64 button from within the Encryption field.
4. Click the Config button to the right of the WEP 64 checkbox.
5. Specify a 4 to 32 character Pass Key and click the Generate button.
6. Use the Key #1-4 areas to specify key numbers.

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.
The WEP 64 screen displays.
The pass key can be any alphanumeric string. The switch, other proprietary routers, and
Brocade clients use the algorithm to convert an ASCII string to the same hexadecimal number.
Clients without Brocade adapters need to use WEP keys manually configured as hexadecimal
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.
