4.4 Configuring a TTY User Interface
The True Type Terminal (TTY) user interface view is a command line view and is used to
configure and manage physical interfaces working in asynchronous and interactive mode.
4.4.1 Establishing the Configuration Task
Before configuring the TTY user interface, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task quickly and accurately.
Applicable Environment
If you need to log in to the router for local maintenance by using a asynchronous serial port, you
can configure the corresponding TTY user interface, including the physical attributes, terminal
attributes, and user priority. The preceding parameters have default values on the router and
additional configuration is not needed. You can configure these parameters as needed.
