H3C WA Series Command Reference Manual page 30

With dynamic WEP encryption configured, the device automatically uses the WEP 104 encryption
method. To change the encryption method, use the cipher-suite command.
With dynamic WEP encryption configured, the WEP key used to encrypt unicast frames is
negotiated between client and server. If the WEP default key is configured, the WEP default key is
used to encrypt multicast frames. If not, the device randomly generates a multicast WEP key.
Related commands: wep key-id, cipher-suite, and wep default-key.
