Release Notes for Cisco Wireless LAN Controllers and Lightweight Access Points for Release 3.2.171.6
OL-11567-02
Important Notes
Apple iBook
Some Apple operating systems require shared key authentication for WEP. Other releases of the
operating system do not work with shared key WEP unless the client saves the key in its key ring. How
you should configure your controller is based on the client mix you expect to use. Cisco recommends
testing these configurations before deployment.

Some Clients See Only 64 Access Point MAC Addresses (BSSIDs) at a Time
In a crowded RF environment, clients may not be able to detect the desired SSID because of internal
table limitations. Sometimes disabling and then enabling the client interface forces a rescan. Your RF
environment needs to be controlled. Cisco UWN rogue access point detection and containment can help
you to enforce RF policies in your buildings and campuses.
Pinging from Any Network Device to a Dynamic Interface IP Address Is Not
Supported
Clients on the WLAN associated with the interface pass traffic normally.
