Command Syntax Conventions

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

  • Boldface indicates commands and keywords that are entered literally as shown.

  • Italics indicate arguments for which you supply actual values.

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

  • Square brackets, [ ], indicate optional elements.

  • Braces, { }, indicate a required choice.

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