Roles and the Associations of Wireless Devices
•
CCKM Fast Secure Roaming with a Central WDS is only available with TKIP encryption when the
universal workgroup bridge is enabled.
When a 2.4 GHz wireless device is configured as a universal workgroup bridge, it does not advertise
•
itself as a Cisco Compatible eXtensions (CCX) client; however, it does support CCX features. The
CCX program (Aironet extensions) delivers advanced WLAN system-level capabilities and
Cisco-specific WLAN innovations to third-party WI-FI-enabled laptops, WLAN adapter cards,
PDAs, WI-FI phones, and application-specific devices (ASDs).
