Command Syntax Conventions
The conventions used to present command syntax in this book are the same conventoins used in the IOS Command
Reference. The Command Reference describes these conventions as follows:
·
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.
·
Boldface indicates commands and keywords that are entered literally as shown. In actual configuration examples
and output (not general command syntax), boldface indicates commands that are manually input by the user (such
as a show command).
·
Italics indicate arguments for which you supply actual values.
