Comm<strong>and</strong> Syntax Conventions<br />
The conventions used to present comm<strong>and</strong> syntax in this book are the same conventions<br />
used in the IOS Comm<strong>and</strong> Reference. The Comm<strong>and</strong> Reference describes these conventions<br />
as follows:<br />
■ Boldface indicates comm<strong>and</strong>s <strong>and</strong> keywords that are entered literally as shown. In<br />
actual configuration examples <strong>and</strong> output (not general comm<strong>and</strong> syntax), boldface<br />
indicates comm<strong>and</strong>s that are manually input by the user (such as a show comm<strong>and</strong>).<br />
■ Italic indicates arguments for which you supply actual values.<br />
■ Vertical bars (|) separate alternative, mutually exclusive elements.<br />
■ Square brackets ([ ]) indicate an optional element.<br />
■ Braces ({ }) indicate a required choice.<br />
■ Braces within brackets ([{ }]) indicate a required choice within an optional element.
