Viewing Access Point Authentication Failure Status

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 WLAN Controller Switch, click
Monitoring > Access Points > Authentication Failed Access Points.

Figure 61. Authentication Failed AP Status

The AP authentication failure list shows information about APs that failed to establish
communication with the D-Link WLAN Controller 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.
To delete the entries for all APs from the failure list, click Delete All. To add an AP from the
access point authentication failure list to the Valid AP database, select the check box next to
the MAC address of the AP and click Manage. If you use the local database for AP
Validation, you can click the Administration > Basic Setup > Valid AP tab to modify the AP
configuration.
If you use a RADIUS server for AP validation, you must add the MAC address of the AP to
the RADIUS server database.
