An AP might fail to associate to the switch due to errors such as invalid packet format or vendor ID, or because the AP is
not configured as a valid AP with the correct local or RADIUS authentication information.
Status entries for failed access points are collected at a point in time and eventually age out. The age value for each entry
shows how long ago the switch recorded the entry. You can configure the age out time for status entries on the
Administration > Advanced Configuration > Global page. You can also manually delete status entries.
To view a list of APs that failed to associate with the D-Link Unified Switch, click Monitoring > Access Points >
Authentication Failed Access Points .
Figure 63: Authentication Failed AP Status
The AP authentication failure list shows information about APs that failed to establish communication with the D-Link Unified
Switch. The AP can fail due to one of the following reasons:
• No Database Entry—The MAC address of the AP is not in the local Valid AP database or the external RADIUS server
database, so the AP has not been validated.
• Authentication—The authentication password configured in the AP did not match the password configured in the local
database or RADIUS database.
Use the buttons at the bottom of the page to perform the following tasks:
• To delete the entries for all APs from the failure list, click Delete All .
• To configure an Authentication Failed AP to be managed by the switch the next time it is discovered, select the check
box next to the MAC address of the AP and click
Manage .
• You will be presented with the Valid Access Point Configuration page. You can then configure the AP and click
Submit to save the AP in the local Valid AP database.
• Click Back to see a list of Authentication Failed Access Points.
• Click Refresh to update the screen with the most current information.
• When the Auto Refresh option is selected, the page will be refreshed after every 30 seconds.
If you use a RADIUS server for AP validation, you must add the MAC address of the AP to the RADIUS server database.
For more information, see Appendix B:, “Configuring the External RADIUS Server” on page 207.
Click the MAC address of the AP to view more information about the AP. If the AP is not a D-Link Access Point, some values
are unknown.
