Cisco Cisco Aironet 350 Wireless LAN Client Adapter

The CB21AG client adapter does no send re-association requests with the CCKM keys when moved 
from controller to another. The adapter sends re-association request with CCKM keys only when it 
roams back to the controller to which it was first attached. This issue occurs when the access point 
is configured to use WPA2 for key management.

This issue can be solved by using WPA key management with TKIP and CCKM.

The following caveat has been resolved in ACAU 3.0.

CSCei67249—WEP key setting in ACAU profile fails to transfer to ADU profile

If you create a profile with a 128-bit static WEP key and choose the Install & Run option under 
Global Settings > Setup Settings > Profile Migration Tool in ACAU and save these settings to the 
CiscoAdminConfig.dat file, this profile is no longer configured for 128-bit static WEP after it is 
loaded into ADU.

If you are a Cisco registered user, you can use the Cisco TAC Software Bug Toolkit, which consists of 
three tools (Bug Navigator, Bug Watcher, and Search by Bug ID Number) that help you identify existing 
bugs (or caveats) in Cisco software products.
