In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "None of the configurations get applied unless the commit-buffer command is used."

Any command-line input or output is written as follows:

switch(config)# feature vpc
switch(config)# feature lacp

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click on the Equipment tab in the navigation pane."
