Configuring RSN security IE
An RSN is a security network that only allows the creation of robust security network associations
(RSNAs). An RSN can be identified by the indication in the RSN Information Element (IE) of beacon
frames. It provides greater protection than WEP and WPA.
To configure RSN security IE:
Step Command Remarks
174. Enter system view. system-view N/A
175. Enter WLAN service
template view.
wlan service-template
service-template-number crypto
N/A
176. Enable the RSN-IE in the
beacon and probe
responses.
security-ie rsn By default, RSN-IE is disabled.
Configuring cipher suite
A cipher suite is used for data encapsulation and de-encapsulation. It uses the following encryption
methods:
• WEP40/WEP104/WEP128
• TKIP
• AES-CCMP
Configuring WEP cipher suite
The WEP encryption mechanism requires that the authenticator and clients on a WLAN have the same
key configured. WEP adopts the RC4 algorithm (a stream encryption algorithm), supporting WEP40,
WEP104 and WEP128 keys.
You can use WEP with either open system or shared key authentication mode:
• In open system authentication mode, the WEP key is used for encryption only and not for
authentication. A client can access the network without having the same key as the authenticator.
However, if the receiver has a different key from the sender, it discards the packets received from the
sender.
• In shared key authentication mode, the WEP key is used for both encryption and authentication. If
the key of a client is different from that of the authenticator, the client cannot pass the authentication
and the access of the client is denied.
To configure WEP encryption:
Step Command Remarks
177. Enter system view. system-view N/A
178. Enter WLAN service
template view.
wlan service-template
service-template-number crypto
N/A
179. Enable the WEP cipher
suite. cipher-suite { wep40 | wep104 |
wep128 } By default, no cipher suite is
selected.
