The client authentication failure status for an individual client shows information about the client that failed to authenticate
or associate with an AP and list the number of authentication or association failures. A client with a high number of failed
authentications might indicate a possible threat to the WLAN.
Table 56
shows the fields on the detail page for Client Authentication Failure Status.
Monitoring and Managing Ad Hoc Clients
An ad hoc client is a wireless client that gains access to the WLAN through a wireless client that is associated with an access
point. The ad hoc client does not communicate directly with the AP. Ad hoc networks are a particular concern because they
consume RF bandwidth and can present a security risk.
Status entries for ad hoc clients 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.
From the
Monitoring > Client > Ad Hoc Clients
page, you can view and manage wireless clients that are connected to the
WLAN through an ad hoc network.
Figure 69: Ad Hoc Clients
•
To delete the ad hoc client entries from the list, click
Delete All
. The status list is cleared on the switch.
•
If you want to block an ad hoc client from WLAN access, select the check box next to the MAC address of the client and
click
Deny MAC
. The MAC address is added to the MAC Deny List in the AP Profile MAC Authentication settings.
Table 56: Client Authentication Failure Status
Field
Description
MAC Address
The Ethernet address of the client.
BSSID
The managed AP VAP Ethernet MAC address on which the client attempted
to associate and/or authenticate.
SSID
The network SSID on which client attempted to associate and/or authenticate.
Last Failure Type
Indicates the last type of failure that occurred, which can be Authentication or
Association.
Authentication Failure Count
Count of authentication failures for this client.
Association Failure Count
Count of association failures for this client.
Age
Time since failure occurred.
Note:
Clearing the list does not disassociate any of the ad hob clients, and the clients might still be involved in
the ad hoc network.
