Resolution
If a high level of security and encryption is required, industry-standard security solutions on Layer2 (L2) can be implemented, such as 802.1X dynamic keys with Extensible Authentication Protocol (EAP) or Wi-Fi Protected Access (WPA) dynamic keys.
The Cisco Wireless LAN (WLAN) Solution WPA implementation includes Advanced Encryption Standard (AES), Temporal Key Integrity Protocol + Message Integrity Code Checksum (TKIP + Michael) dynamic keys, or Wired Equivalent Privacy (WEP) static keys.
To automatically block L2 access after an operator-set number of failed authentication attempts, this feature can be disabled. Regardless of the wireless security solution selected, all L2 wired communications between Cisco WLAN Controllers and Cisco 1000 Series Lightweight Access Points (APs) are secured because data is passed through LWAPP tunnels.
For more information on the security options available on Cisco WLAN Controllers, refer to the Security Overview section of Configuring Security Solutions.
