What is the use of the excessive authentication failure setting in a Wireless LAN Controller (WLC)?
A. This setting is one of the client exclusion policies. The client exclusion is a security feature on the controller. The policy is used to blacklist clients in order to prevent illegal access to the network or attacks to the wireless network. With this excessive web authentication failure policy enabled, when a client’s number of failed web authentication attempts exceeds 5, the controller considers that the client has exceeded the maximum attempts of web authentication and blacklists the client. Complete these steps in order to enable or disable this setting: • From the WLC GUI, go to Security > Wireless Protection Policies > Client Exclusion Policies. • Check or uncheck Excessive Web Authentication Failures.
