2 Planning the D-Link Unified Access System Network

Since the D-Link WLAN Controller Switch has Layer 2/3 switching functions as well as WLAN data and management functions, you can connect D-Link Access Points, wired PCs, or other network equipment such as hubs, routers, or other switches directly to the 10/100 Mbps Ethernet ports on the switch. All connections to the D-Link WLAN Controller Switch must be wired connections since the switch does not have any radios.

In Figure 8, the D-Link WLAN Controller Switches are both LAN and WLAN switches that handle traffic from end users connected to the wired LAN as well as traffic from the D-Link Access Points. In the diagram, Building 1 and Building 2 have a D-Link WLAN Controller Switch on each floor.

The four D-Link WLAN Controller Switches are in the same peer group. This allows wireless clients to roam between floors and between buildings without the need to re-authenticate. Additionally, each WCS shares its list of managed APs and wireless clients with the switches in the peer group so that the APs and wireless clients are not reported as rogues (unknown).

The topology in Figure 8 works well if you need to add, upgrade, or replace LAN switches on your network.
