R21xx-HP FlexFabric 11900 Fundamentals Command Reference

28
Usage guidelines
This command sets the maximum number of lines that can be displayed on one screen when the screen
pause function is enabled. If the screen pause function is disabled, the system displays command output
without any pause.
The actual number of lines that can be displayed on a screen is restricted by the display specification of
the configuration terminal. For example, if the display specification is 24 lines but the specified maximum
number of lines for a screen is 40, the device sends 40 lines to the screen at a time but only the last 24
lines are displayed on the screen. To view the previous 16 lines, you must press PgUp.
The screen pause function is enabled by default. To disable this function, execute the screen-length 0
command or the screen-length disable command.

# Set the maximum number of lines to be displayed on a screen to 30 for user interface VTY 0.
<Sysname> system-view
