Usage Scenario
When you log in to the device from a console interface and run the display interface description [ interface-type [ interface-number ] ] command to view the interface information, output information does not automatically change to another line, resulting in wrong format of the output information.
To resolve this problem, run the screen-width command to adjust the information format. In general, you do not need to adjust the number of columns displayed on the terminal screen. Setting the number of columns displayed on a screen is not recommended.
Precautions
The number of columns set using the screen-width command is valid only for the current interface. The setting is not saved after you log out. When you log in to the device from the console interface and configure this command, the number of columns displayed on the terminal screen is valid only for the current console interface, which has no impact on other users who log in to the device from the VTY interface or other interfaces. If you log out of the console interface and log in to the device again, the default width is used for the terminal screen.
This command is valid only for information displayed by the display interface description [ interface-type [ interface-number ] ] command.
