D-Link Unified Access System User Manual Figure 9 shows two D-Link Unified Switches in the network data center. In this deployment, the switches do not connect directly to APs or end-user nodes. Figure 9. Data Center Topology LAN Switch Unified Switches APs Network Backbone LAN Switch Data Center APs The data center topology is a good solution in networks where the goal is to add a wireless LAN to a network with minimal changes to the existing network. Traffic from wireless clients to the APs is either tunneled through the Unified Switch or tagged with a VLAN ID by the AP and handled accordingly. If the traffic is tagged, it might not pass through the Unified Switch. Access Point-to-Switch Discovery To enable the AP and Unified Switch to discover each other, you can use one of the following four methods: • Enter the IP address of the Unified Switch into the AP • Enter the IP address of the AP into the Unified Switch • Configure the DHCP server to pass the IP address of the Unified Switch to the AP in DHCP option 43 • Use the D-Link Wireless Device Discovery Protocol The AP-to-switch discovery method you use depends on your network topology. For example, if the Unified Switch and AP are in the same Layer 2 multicast domain, we recommend that you use the D-Link Wireless Device Discovery Protocol. These options are discussed in more detail in "Discovering Access Points and Peer Switches" on page 61. Access Point Placement D-Link Access Points can be on the same subnet as the switch or on a different subnet. You can connect the AP directly to the Unified Switch or to another networking device.
