Example 1: L2 Discovery
In <Link>Figure 32, the AP and Unified Switch are directly connected. The devices are in the same layer 2 broadcast domain
and use the default VLAN settings. After both devices acquire an IP address, either statically or through DHCP, the Unified
Switch automatically discovers the AP through its broadcast of a L2 discovery message.
Access Point
In this example, the administrator does not need to configure any discovery information on the AP or the Unified Switch. 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
Example 2: IP Address of AP Configured in the Switch
Figure 33 shows two access points. One AP is directly connected to the D-Link Unified Switch, and the other AP is connected
via a L3 switch.
Access Point 1
IP: 192.168.1.12
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 Unified Switch 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
Switch" on page 66.
