To view the IP discovery status of the devices you add to the IP List, such as whether the switch successfully 

polled the IP address you entered, navigate to the 

WLAN > Monitoring > Global > IP Discovery tab.

L2/VLAN Discovery

The D-Link Wireless Device Discovery Protocol is a good discovery method to use if the DWS-4000 Series switch 

and APs are located in the same Layer 2 multicast domain. The DWS-4000 Series switch periodically sends a 

multicast packet containing the discovery message on each VLAN enabled for discovery. You can enable the 

discovery protocol on up to 16 VLANs.

By default, VLAN 1 is enabled on the AP, and VLAN 1 is enabled for discovery on the DWS-4000 Series switch. 

If the switch and AP are in the same Layer 2 multicast domain, you might not need to take any action to enable 

AP-to-DWS-4000 Series switch discovery. The DWS-4000 Series switch also uses L2/VLAN discovery to find 

peer switches within the L2 multicast domain.
