The RSN settings appear at the bottom of the output.

Note. The RSN-related fields appear in the show service-profileoutput only when RSN is enabled.

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-listradio {1 2} radio-profile name mode {enable disable}

To map service profile rsn to radio profile bldg2, type the following command:

23x0# 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 ports 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. AP access ports 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.

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 203.)
