D-Link Unified Access System User Manual its association unless the connectivity to the current Unified Switch fails or the switch tells the AP to disassociate and associate with another switch. The following sections describe each discovery mechanism. D-Link Wireless Device Discovery Protocol The Wireless Device Discovery Protocol is part of the D-Link Wireless AP Protocol (DWAPP). It is a good discovery method to use if D-Link Unified Switches and D-Link Access Points are located in the same Layer 2 multicast domain. The D-Link 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-Switch discovery. If the switch has discovered a new AP by using L2 discovery and the MAC address of the AP is not in the Valid AP database, the AP appears in the list on the Monitoring > Access Point > Authentication Failed Access Points page. To view AP authentication failures from the CLI, enter show wireless ap failure status in Privileged EXEC mode. 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. Use the following procedures to add a VLAN to the discovery list by using the Web interface: 1. Use a browser to log on to the D-Link Unified Switch. 2. From the Navigation menu, click Administration > Basic Setup, then select the Discovery tab. 3. Make sure the box for L2/VLAN Discovery is selected and add the management VLAN ID of an AP or peer switch to the VLAN (1-4094) field. 4. Click Add to add the VLAN to the list. 5. Click Submit to apply the changes. 68 © 2001- 2008 D-Link Corporation. All Rights Reserved.
