I Cannot Log In to the AR Router. How Is this Problem Solved?
1. By default, a user cannot log in to the AR router. You need to run the authentication-mode command in the VTY view to set the authentication mode.
2. To obtain more operation rights, run the user privilege level command in the VTY view to set the user level.
3. To enable the system to disconnect a user from the VTY interface when the timeout period expires, run the idle-timeout command in the VTY view to set the timeout period.
