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 moves 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 reauthentication interval (dot1x reauthentication).
Use this command in Configuration Terminal Batch mode to configure the authentication failure in a dual-homing
setup.
