Preface

This guide includes information on configuring the Cisco Global Site Selector platform (GSS) from the primary GSSM GUI to perform global server load balancing. Certain global server load-balancing tasks require that you use the GUI, other tasks require that you use the CLI. In most cases, you have the option of using either the GUI or the CLI at the primary GSSM. Tasks that require you to use the CLI (configuring sticky groups, for example), are also described in this document.
