Blacklisting Users Dynamically
The clients can be blacklisted dynamically when they exceed the authentication failure
threshold or when a blacklisting rule is triggered as part of the authentication process.
Authentication Failure Blacklisting
When a client takes time to authenticate and exceeds the configured failure threshold, it is
automatically blacklisted by an AP.
Session Firewall-Based Blacklisting
In session firewall-based blacklisting, an ACL rule is used to enable the option for dynamic
blacklisting. When the ACL rule is triggered, it sends out blacklist information and the client is
blacklisted.

To set a blacklist duration:
1. Click the
