In this book, you will find a number of styles of text 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:
"To save or write an image, we can use the imsave() function."
A block of code is set as follows:
Router(config)# interface GigabitEthernet 0/1
Router(config-if)# description To_Switch_Gig_0/1
Router(config-if)# ip addr 10.1.1.1 255.255.255.0
Router(config-if)# ip local-proxy arp
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
Switch(config)# interface GigabitEthernet 0/1
Switch(config-if)# description User_facing_port
Switch(config-if)# storm-control broadcast level 5.00
Switch(config-if)# storm-control unicast level 80.00
Switch(config-if)# storm-control action trap
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes, for example, appear in the text like this: "Clicking the Next button moves you to the next screen."
