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.
Table 325: L3 VLAN Discovery
Field Description
L3/IP Discovery Select or clear this option to enable or disable IP-based discovery of access points
and peer wireless switches. When the L3/IP Discovery option is selected, IP polling is
enabled and the switch will periodically poll each address in the configured IP List. By
default, L3/IP Discovery is enabled.
IP List Shows the list of IP addresses configured for discovery.
To remove entries from the list, select one or more entries and click Delete. There
are no default entries, and the maximum number of entries supported is 256.
IP Address Range This text field is used to add a range of IP address entries to the IP List. Enter the IP
address at the start of the address range in the From field, and enter the IP address
at the end of the range in the To field, then click Add. All IP addresses in the range
are added to the IP List. Only the last octet is allowed to differ between the From
address and the To address.
Note: To add a single IP address, enter the address in the From field and leave the To
field blank, then click Add.
Once all desired entries are added, click Submit to save the list in the running
configuration.

When this option is selected, L2 discovery is enabled and the switch will periodically
broadcast L2 discovery packets on each VLAN in the configured VLAN List. By default,
L2/VLAN Discovery is enabled.
VLAN List Shows the list of VLANs configured for L2 discovery.
To remove entries from the list, select one or more entries and click Delete. By

maximum number of entries supported is 16, and there must be at least one VLAN
configured in the list.
