CardBus (CB21AG), or PCI (PI21AG).
New Features
The Desktop Utility (ADU) version 4.0 release enhances Cisco’s secure wireless solution with the
addition of version 5.0 of Cisco Client Extensions (CCX).
Cisco Client Extensions (CCX) v5.0 including the following highlights:
●
Client troubleshooting, diagnostics, and reporting
The capability to more quickly diagnose network access problems can reduce the total cost
of ownership of a wireless local area network. The diagnostic features enable an end-to-
end troubleshooting capability within Cisco’s wireless LAN infrastructure. The network
managed test feature in the diagnostics tab of the ADU requires software release 4.2 on
Cisco’s Wireless LAN Controller.
●
Management Frame Protection
Management Frame Protection (MFP) enables a more secure wireless solution by
encrypting management frames sent between the client and the wireless LAN.
Management frame protection requires software release 4.1.181 or later on Cisco’s
Wireless LAN Controller.
