System Overview

The WS 2000 Wireless Switch provides a low-cost, feature-rich wireless switch 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. Once 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 three 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-MCM

•WPA
