  If the "Too many clients or invalid access" message is displayed, it indicates that the number of login users has reached the maximum allowed number of login users of the device. In this case, wait a while and try to log in again.
• If the "%enable operation is locked by login-secure service" message is displayed, it indicates that the number of enable password input errors exceeds the number of continuous login authentication failures. If the number of enable password input errors reaches the number specified by the system, the system rejects the login connection request from the IP address during the specified time.
• If the "Password required, but none set" message is displayed, it indicates that no login password has been configured.
