deployment that utilizes three peer switches. Each peer switch can manage up to 48 access points. The WCS and the APs it manages do not need to be on the same subnet.

Peer switches share information about APs and allow Layer 3 roaming among them. To support this, peer switches establish IPv4 tunnels so that the wireless client keeps the same IP address even when the client associates with an access point in a different subnet. The Layer 3 roaming service allows wireless phone users to roam between access points connected to different subnets without dropping calls.

Understanding the User Interfaces

The D-Link Unified Access System enables centralized management of multiple wireless access points, which not only facilitates deployment and management, but also enhances security. The D-Link Unified Access System includes a set of comprehensive management functions for managing and monitoring the WLAN by using one of the following three methods:

•Web-based

•Command-Line Interface (CLI)

•Simple Network Management Protocol (SNMP)

Each of the standards-based management methods enables you to configure, manage, and control the components of the D-Link Unified Access System locally or remotely. Management is standards-based, with configuration parameters and a private MIB that provides control for functions not completely specified in the standard MIBs.

The method you use to configure and monitor the D-Link WLAN Controller Switch depends on your network size and requirements, and on your preference.
