Usage
Information
If the host responds to 802.1X with an incorrect login/password, the login fails. The switch attempts to
authenticate again until the maximum attempts configured is reached. If the authentication fails after all
allowed attempts, the interface is moved to the authentication failed VLAN.
After the authentication VLAN is assigned, the port-state must be toggled to restart authentication.
Authentication occurs at the next re-authentication interval (dot1x reauthentication).
