Cisco AIR-CB21AG-A-K9 Aironet 802.11a/b/g CardBus

Item Description
Cisco Aironet 802.11a/b/g CardBus Adapter FCC Config. MODEL: AIR-CB21AG-A-K9 VENDOR: CISCO FEATURES: Cisco Aironet 802.11A/B/G Wireless Cardbus Adapter Whether configured to support single 802.11b coverage single 802.11g coverage single 802.11a coverage dual-mode 802.11a/g coverage or trimode 802.11a/b/g coverage the Cisco Aironet 802.11a/b/g Wireless CardBus Adapter is Wi-Fi-compliant and combines the freedom of wireless connectivity with 802.11i/Wi-Fi Protected Access 2 (WPA2) encryption for the performance security and manageability that businesses require. Designed with enterprise-class security requirements in mind the Cisco Aironet 802.11a/b/g Wireless CardBus Adapter uses the 802.1X standard for port-based network access. A full array of Extensible Authentication Protocol (EAP) types for user-based authentication together with enterprise-caliber Advanced Encryption Standard (AES) encryption provide full 802.11i support. The adapter supports WPA2-the Wi-Fi Alliance certification for interoperable standards- based wireless LAN security. The Cisco Aironet 802.11a/b/g Wireless CardBus Adapter supports the most common 802.1X authentication types including EAP-Flexible Authentication via Secure Tunneling (EAP-FAST) Cisco LEAP EAP- Transport Layer Security (EAP-TLS) Protected Extensible Authentication Protocol-Generic Token Card (PEAP-GTC) and PEAP- Microsoft Challenge Handshake Authentication Protocol version 2 (PEAP-MSCHAPv2). A wide selection of RADIUS servers such as the Cisco Secure Access Control Server (ACS) and Cisco Access Registrar server can be used for enterprise-class centralized user management that includes: - Strong mutual authentication to help ensure that only legitimate clients associate with legitimate and authorized network RADIUS servers via authorized access points. - Dynamic per-user per-session encryption keys that automatically change on a configurable basis to protect the privacy of transmitted data. - Stronger encryption keys provided by Temporal Key Integrity Protocol (TKIP) enhancements such as message integrity check (MIC) per-packet keys via initialization vector hashing and broadcast key rotation. - RADIUS accounting records for all authentication attempts - IEEE 802.11i/WPA2 AES support Cisco Wireless Security Suite IEEE 802.1X support including Cisco LEAP PEAP-GTC PEAP-MSCHAPv2 and EAP-TLS for mutual authentication with dynamic per-user per-session encryption keys via TKIP enhancements. Full support for WPA. Ready for IEEE 802.11i/WPA2 AES support. Enhanced Client Network Management Bundled with comprehensive easy-to-use client network management utilities to provide a secure intuitive and convenient way to manage and configure the adapter. Cisco LEAP Single Sign-on Convenient option to use login credentials for LEAP sign-on on the users network eliminating the need to enter a second set of credentials. Cisco Wireless Domain Services (WDS) Cisco WDS is a collection of Cisco IOS Software features that enhance wireless LAN client mobility and simplify wireless LAN deployment and management. Cisco WDS includes radio management aggregation fast secure roaming client tracking and WAN link remote site survivability. Site Survey Utility The site survey utility can assist in conducting site surveys as well as troubleshooting existing RF wireless LANs. The utility operates at the RF level and is used to determine the best placement and coverage (overlap) for the network s infrastructure devices. Fast Secure Roaming Allows authenticated client devices to roam securely from one access point to another within or across subnets without any perceptible delay during reassociation. Provides support for latency-sensitive applications such as voice over IP (VoIP) enterprise resource planning (ERP) and Citrix.
