380 Configuring user encryption

NN47250-500 (Version 03.01)
Static WEP encryption is disabled by default. To enable static WEP encryption, configure the static WEP keys
and assign them to unicast and multicast traffic. Make sure you configure the same static keys on the clients.
To support dynamic WEP in a WPA environment, enable WPA and enable the WEP-40 or WEP-104 cipher
suite. (See “Configuring WPA” on page 373.)
This section describes how to configure and assign static WEP keys. (To change other key-related settings, see
“Managing 802.1X encryption keys” on page 651.)
Figure 24 shows an example of a radio configured to provide static and dynamic WEP encryption for
non-WPA clients. The radio uses dynamically generated keys to encrypt traffic for dynamic WEP clients. The
radio also encrypts traffic for static WEP clients whose keys match the keys configured on the radio.
