D-Link Unified Access System User Manual
address, either statically or through DHCP, the WCS automatically discovers the AP through
its broadcast of a L2 discovery message.
Figure 30. L2 Discovery Example
In this example, the administrator does not need to configure any discovery information on the
AP or the WCS. The L2 discovery works automatically when the devices are directly
connected or connected by using a layer 2 bridge.
For more information about this discovery method, see “D-Link Wireless Device Discovery
Protocol” on page 64.
Example 2: IP Address of AP Configured in the Switch
Figure 31 shows two access points. One AP is directly connected to the D-Link WLAN
Controller Switch, and the other AP is connected via a L3 switch.
Figure 31. L3 Discovery Example 1
The administrator disables the L2 discovery method on the switch and adds the IP addresses of
the APs to the L3 Discovery list on the switch. The WCS sends UDP discovery messages to
the IP addresses in its list. When the AP receives the messages and decides that it can connect
to the switch, it initiates an SSL TCP connection to the switch.
For information about how to configure this discovery method, see “Configuring IP Addresses
of Peers and APs in the Switch” on page 65.
