Displaying RSN settings
To display the RSN settings in a service profile, use the following command:
show service-profile {name | ?}
The RSN settings appear at the bottom of the output.
Assigning the service profile to radios and enabling the radios
After you configure RSN settings in a service profile, you can map the service profile to a radio profile, assign the radio
profile to radios, and enable the radios to activate the settings.
To map a service profile to a radio profile, use the following command:
set radio-profile name service-profile name
To assign a radio profile to radios and enable the radios, use the following command:
set ap port-list radio {1 | 2} radio-profile name mode {enable | disable}
To map service profile rsn to radio profile bldg2, type the following command:
WSS# set radio-profile blgd2 service-profile rsn
success: change accepted.
Configuring WEP
Wired-Equivalent Privacy (WEP) is a security protocol defined in the 802.11 standard. WEP uses the RC4 encryption
algorithm to encrypt data.
To provide integrity checking, WEP access points and clients check the integrity of a frame’s cyclic redundancy check
(CRC), generate an integrity check value (ICV), and append the value to the frame before sending it. The radio or client
that receives the frame recalculates the ICV and compares the result to the ICV in the frame. If the values match, the
frame is processed. If the values do not match, the frame is discarded.
WEP is either dynamic or static depending on how the encryption keys are generated. APs support dynamic WEP and
static WEP.
• For dynamic WEP, WSS Software dynamically generates keys for broadcast, multicast, and unicast traffic. WSS
Software generates unique unicast keys for each client session and periodically regenerates (rotates) the broadcast
and multicast keys for all clients. You can change or disable the broadcast or multicast rekeying interval.
• For static WEP, WSS Software uses statically configured keys typed in the WSS switch’s configuration and on the
wireless client and does not rotate the keys.
Dynamic WEP encryption is enabled by default. You can disable dynamic WEP support by enabling WPA and leaving
the WEP-40 or WEP-104 cipher suites disabled. If you use dynamic WEP, 802.1X must also be configured on the client
in addition to WEP.
Note. The RSN-related fields appear in the show service-profile output only when
RSN is enabled.
