System Overview
The WS 2000 Wireless Switch provides a low-cost, feature-rich option for sites with one to six Access Ports. The WS 2000
Wireless Switch works at the center of a network’s infrastructure to seamlessly and securely combine wireless LANs
(WLANs) and wired networks. The switch sits on the network. Wireless Access Ports connect to one of the six available
ports on the switch and the external wired network (WAN) connects to a single 10/100 Mbit/sec. WAN port.
Mobile units (MUs) associate with the switch via an Access Port. When an MU contacts the switch, the switch cell controller
services attempt to authenticate the device for access to the network.
The WS 2000 Wireless Switch acts as a WAN/LAN gateway and a wired/wireless switch.
Management of Access Ports
This wireless switch provides six 10/100 Mbit/sec. LAN ports for internal wired or wireless traffic. Four of these ports
provide IEEE 802.3af-compliant Power over Ethernet (PoE) support for devices that require power from the Ethernet
connection (such as Access Ports). Administrators can configure the six ports to communicate with a private LAN or with an
Access Port for a wireless LAN (WLAN). The switch provides up to four extended service set identifiers (ESSIDs) for each
Access Port connected to the switch.
Firewall Security
The LAN and Access Ports are placed behind a user-configurable firewall that provides stateful packet inspection. The
wireless switch performs network address translation (NAT) on packets passing to and from the WAN port. This combination
provides enhanced security by monitoring communication with the wired network.
Wireless LAN (WLAN) Security
Administrators can configure security settings independently for each ESSID. Security settings and protocols available with
this switch include:
• Kerberos
•WEP-40
• WEP-128
• 802.1x with RADIUS
• 802.1x with Shared Key
•KeyGuard
•WPA
• WPA2/CCMP
VPN Security
Virtual Private Networks (VPNs) are IP-based networks that use encryption and tunneling to give users remote access to a
secure LAN. In essence, the trust relationship is extended from one LAN across the public network to another LAN, without
sacrificing security. A VPN behaves similarly to a private network; however, because the data travels through the public
network, it needs several layers of security. The WS 2000 Wireless Switch acts as a robust VPN gateway.
