Command Syntax Conventions

Command Syntax Conventions

The conventions used to present command syntax in this book are the same conventions used in the IOS Command Reference. The Command Reference describes these conventions as follows:

  • Boldface indicates commands and keywords entered literally as shown. In actual configuration examples and output (not general command syntax), boldface indicates commands manually input by the user (such as a show command).

  • Italic indicates arguments for which you supply actual values.

  • Vertical bars (|) separate alternative, mutually exclusive elements.

  • Square brackets ([ ]) indicate an optional element.

  • Braces ({ }) indicate a required choice.

  • Braces within brackets ([{ }]) indicate a required choice within an optional element.
