Explanation:
The Cisco Compatible Extensions program ensures the widespread availability of client
devices that are interoperable with a Cisco WLAN infrastructure and take advantage of
Cisco innovations for enhanced security, mobility, quality of service, and network
management. Cisco Compatible client devices are sold and supported by their
manufacturers, not Cisco.
Versions and Features
There are four versions of the Cisco Compatible specification; each version builds upon its
predecessors. With a few exceptions, every feature that must be supported in one version
also must be supported in each subsequent version.
Features of Cisco Compatible V1 include:
Compliance with IEEE 802.11 and Wi-Fi
Support for the 802.1X authentication type: Cisco LEAP
Ability to interoperate with an access point that supports multiple Service Set Identifiers
(SSIDs) tied to multiple VLANs, providing benefits such as flexible security schemes in a
mixed client environment
Features of Cisco Compatible V2 include:
Compliance with Wi-Fi Protected Access (WPA), including support for WPA Temporal Key
Integrity Protocol (TKIP) encryption
Support for the 802.1X authentication type: Protected EAP (PEAP) with EAP-GTC
Fast, secure roaming through support of the 802.1X key management protocol: Cisco
Centralized Key Management (CCKM)
Radio frequency (RF) scanning, with scanned data sent to the access point and ultimately to
CiscoWorks Wireless LAN Solution Engine (WLSE) for analysis and performance of RF
management functions such as intrusion detection, assisted site survey, and detection of
interference sources
Features of Cisco Compatible V3 include:
Compliance with WPA 2, including support for Advanced Encryption Standard (AES)
encryption

Support for the 802.1X authentication type: EAP-FAST
Support for Wi-Fi Multimedia (WMM), a subset of the IEEE 802.11e quality of service (QoS)
standard defined by the Wi-Fi Alliance
Features of Cisco Compatible V4 include:
Support of Cisco Network Admission Control
Call admission control – addressing voice over IP (VoIP) stability, roaming, and other
QoSrelated issues
Support for a power-saving mechanism, U-APSD, in QoS environments
VoIP metrics for reporting to optimize WLAN VoIP performance
Enhanced roaming
Ability to function as an 802.11 location tag
