5.3.8 KeyGuard
KeyGuard is a proprietary encryption method developed by Symbol Technologies. KeyGuard is Symbol’s
enhancement to WEP encryption and can work with any WEP device. This encryption method rotates WEP
keys for devices that support the method. This encryption implementation is based on the IEEE Wireless
Fidelity (Wi-Fi) standard, 802.11i.
1. Select the KeyGuard radio button to enable the KeyGuard encryption method.
2. To use KeyGuard encryption with the No Authentication selection, click the MCM Key Settings button
to display a sub-screen for entering keys. (Note that these are the same keys specified for WEP
encryption.
3. Select a Key # radio button to enter to enter or change a passkey.
4. Specify a pass key string in the Pass Key field. The pass key can be any alphanumeric string. The switch,
other proprietary routers, and Symbol cards in mobile units (MUs) use an algorithm to convert an ASCII
string to the same hexadecimal number, but this conversion is not required for a wireless connection.
5. Click the Generate button and the pass key will be entered in the appropriate Key # field.
6. When finished entering pass keys, click the Ok button to close this screen.
7. Click the Apply button on the WLAN Security screen to save changes.
5.3.9 No Encryption
If No Authentication is selected, the No Encryption radio button can disable encryption on this WLAN. If
security is not an issue, this setting avoids the overhead that an encryption protocol demands on the switch’s
processor.
5.3.10 IP Filtering
IP based filtering allows administrators to configure Incoming and Outgoing IP filtering policies on packets
within the same Subnet / WLAN and between wired and wireless hosts.
