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.
