Cisco 3200 Series Wireless MIC Software Configuration Guide
OL-7734-02
Chapter 1 Overview
Features
• Enhanced security—Enable three advanced security features to protect against sophisticated attacks
on your wireless network's WEP keys: Message Integrity Check (MIC) and WEP key hashing.
Enhanced security for WPA/TKIP is also available.
• Enhanced authentication services—Set up non-root bridges or workgroup bridges to authenticate to
the network like other wireless client devices. After a network username and password for the
non-root bridge or workgroup bridge are set, it authenticates to the network using Cisco Light
Extensible Authentication Protocol (LEAP), and receives and uses dynamic WEP keys.
• Advanced Encryption Standard (AES) (only available on the 4.9-GHz WMIC)—This feature
supports Advanced Encryption Standard-Counter Mode with Cipher Block Chaining Message
Authentication Code Protocol (AES-CCMP). AES-CCMP is required for Wi-Fi Protected Access 2
(WPA2) and IEEE 802.11i wireless LAN security.
• Enhanced authentication for Cisco Centralized Key Management (CCKM).
• Fast, secure roaming of client devices, and radio management through wireless domain services
(WDS) (See the “Configuring WDS, Fast Secure Roaming, and Radio Management” chapter for
more information.
Note The 4.9-GHz WMIC does not support CKIP and CMIC encryption; however, The 2.4-GHz WMIC does
support CKIP and CMIC encryption.
The key differences between the 2.4-GHz WMIC and the 4.9-GHz WMIC are shown in Table 1-1.
