Configuring WLANs
Step 10 Reenable the 802.11a and 802.11b/g networks so that you can configure the QoS profiles. Enter these
commands:
config 802.11a enable network
config 802.11b enable network
Configuring Cisco Client Extensions
Cisco Client Extensions (CCX) software is licensed to manufacturers and vendors of third-party client
devices. The CCX code resident on these clients enables them to communicate wirelessly with Cisco
access points and to support Cisco features that other client devices do not, including those related to
increased security, enhanced performance, fast roaming, and superior power management.
The 4.0 release of controller software supports CCX versions 1 through 4, which enables controllers and
their access points to communicate wirelessly with third-party client devices that support CCX. CCX
support is enabled automatically for every WLAN on the controller and cannot be disabled. However,
you can configure a specific CCX feature per WLAN. This feature is Aironet information elements (IEs).
If Aironet IE support is enabled, the access point sends an Aironet IE 0x85 (which contains the access
point name, load, number of associated clients, and so on) in the beacon and probe responses of this
WLAN, and the controller sends Aironet IEs 0x85 and 0x95 (which contains the management IP address
of the controller and the IP address of the access point) in the reassociation response if it receives Aironet
IE 0x85 in the reassociation request.
Follow the instructions in this section to configure a WLAN for the CCX Aironet IE feature and to see
the CCX version supported by specific client devices using either the GUI or the CLI.
Note CCX is not supported on the AP1030.
Using the GUI to Configure CCX Aironet IEs
Follow these steps to configure a WLAN for CCX Aironet IEs using the GUI.
Step 1 Click WLANs to access the WLANs page.
Step 2 Click the Edit link of the desired WLAN to access the WLANs > Edit page (see Figure 6-6).
