“Terminal Length” Indicates the length of the lines that are displayed when a command is issued, in this situation we want the configuration to appear without any breaks when we issue the “#Show Run” command.

“400” indicates the amount of lines that can be displayed before the terminal window breaks and asks the user to either press space/enter to display the next line/page. This range can be between 2-1000
