Run the screen-length screen-length [ temporary ] command in the user view or user interface view to set the number of rows to be displayed on a screen. The parameter temporary is mandatory when you run this command in the user view and specifies the number of rows to be temporarily displayed on a terminal screen. The default number of rows is 24.

In V200R005 and earlier versions, run the screen-width screen-length command in any view to set the number of columns to be displayed on the screen. The default number of columns is 80. Each character is a column. In versions after V200R005, the number of columns displayed on a terminal screen cannot be set using this command. The device automatically adjusts the number of columns displayed on a terminal screen.
