Transparent AP-to-Switch Connectivity
There is no need to create new VLANs and IP subnets in every wiring closet switch for wireless APs
and users because Alcatel OmniAccess Access Points uniquely forward 802.11 traffic to Alcatel
OmniAccess WLAN switches across any L2/L3 wired network using standard generic routing
encapsulation (GRE) tunnels. Wireless VLANs only need to be created inside the centralized WLAN
switches for segmenting 802.11 traffic according to user roles and SSIDs.
Centralized Wireless Security Protects the Air, the Data, the Network, and the User
Alcatel OmniAccess WLAN switching system uniquely delivers multi-layered wireless security that
protects the air, the data, the network, and the users. A patented classification engine coupled with
sophisticated RF monitoring lets administrators protect the air by automatically detecting unauthorized
users, containing rogue APs and ensuring users don’t associate with interfering APs. Link layer security,
with support for WEP, dynamic WEP, TKIP (WPA 1.0), and AES protects user data.
Port-based 802.1x authentication is used with standard authentication mechanisms such as RADIUS,
LDAP, or Active Directory, and combined with link layer encryption to ensure user privacy. Network
layer security lets enterprises terminate IPSec VPN tunnels at LAN speeds inside the corporate intranet.
An integrated firewall lets administrators create and enforce stateful policies that follow users.
Secure Mobility
The Alcatel OmniAccess WLAN switches give users of wireless laptops, PDAs, and other 802.11
mobile devices secure access while moving within and between campus buildings and corporate
subnets. With an integrated stateful firewall that can be applied on a per-user basis, administrators
establish unique access, service, and security policies for different users or user groups. Policies are
based on any combination of parameters such as user, group, duration, time-of-day and location.
These policies are centrally configured and propagated throughout the network so administrators can
enforce desired levels of security and QoS for users as they move.
L2 and L3 mobility between APs, subnets, and WLAN switches using proxy DHCP and proxy mobile IP
eliminates lost sessions and the need for users to re-authenticate. No mobile IP software is required on
client stations.
Authentication and Access Control
The Alcatel OmniAccess WLAN switches support MAC and IP based user authentication methods
including the IEEE 802.1x framework that allows the use of PEAP, EAP-TLS, and EAP-TTLS with RADIUS,
and IPSec VPNs using PPP or L2TP with CHAP or MS-CHAP. In addition, users can be authenticated
against existing LDAP, RADIUS, or Windows domain servers as well as a local database inside the
Alcatel OmniAccess WLAN switch.
