L2/Vlan Discovery; Profile; Table 258: L3 Vlan Discovery - D-Link DWS-4026 User Manual

D-Link Unified Access System
If an AP has already been discovered through another method, the Unified Switch will not poll the IP
address of the AP.

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 Unified Switch and APs are located
in the same Layer 2 multicast domain. The Unified 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 Unified 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-Unified Switch discovery.
The Unified Switch also uses L2/VLAN discovery to find peer switches within the L2 multicast domain.
The APs process the discovery message only when it comes in on the management VLAN. The APs do not forward the L2
discovery messages onto the wireless media.
From the Unified Switch, you can check the discovery status of APs and peer switches. To view information about whether
the switch discovered any APs, navigate to the WLAN > Monitoring > Access Point > Managed AP Status page. If you
have not added the MAC address of the AP to the local or RADIUS Valid AP database, the AP appears in the WLAN >
Monitoring > Access Points > AP Authentication Failure Status list, and the failure type is listed as No Database Entry.
To view information about whether the switch discovered any peer switches, navigate to the WLAN > Monitoring > Peer
Switch page.

The switch can support APs that have different hardware capabilities, such as the supported number of radios and the
supported IEEE 802.11 modes. APs that use the same profile should have the same hardware capabilities so that the

Table 258: L3 VLAN Discovery

Description
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.
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.
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.
