Conventions

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: "This will list all the nodes under the opendaylight-inventory subtree of MD-SAL that stores OpenFlow switch information."

A block of code is set as follows:

<node xmlns="urn:TBD:params:xml:ns:yang:network-topology"> 
<node-id>new-netconf-device</node-id> 
  <host xmlns="urn:opendaylight:netconf-node-topology">127.0.0.1</host> 
  <port xmlns="urn:opendaylight:netconf-node-topology">17830</port> 
  <username xmlns="urn:opendaylight:netconf-node-topology">admin</username> 
  <password xmlns="urn:opendaylight:netconf-node-topology">admin</password> 
  <tcp-only xmlns="urn:opendaylight:netconf-node-topology">false</tcp-only> 

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

$ ./bin/karaf 

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: "If prompted, choose to select the Insecure connection option."
