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:
Bold indicates commands and keywords that are entered literally as shown.
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.
