Information
If a connection remains idle for a time out period, the system automatically terminates the connection. By default, the idle timeout is 5 minutes.\n\nIf all user-interfaces are configured for authentication and there is a FAILED result, this could be a result of the 'user-interfaces maximum-vty' is configured for more terminals than are configured.
Solution
In system view, undo or lower the idle time out for any user interfaceses by:\n\n undo idle-timeout <minutes> [<seconds>]
