Document Organization
This document contains the following chapters and appendices.
Chapter or Appendix
Description
Chapter 1, “Ethernet-to-the-Factory Solution
Overview.”
Provides and overview of the Cisco
Ethernet-to-the-Factory solution.
Chapter 2, “Solution Architecture.”
Provides an overview of the EttF solution
architecture, as a means to describe the various
systems, components, and their relation to each
other to give context to the networking function and
technical requirements.
Chapter 3, “Basic Network Design.”
Provides guidelines and best practices for IP
addressing, and the selection of routing protocols
based on the manufacturing zone topology and
server farm access layer design.
Chapter 4, “Implementation of the Cell/Area
Zone .”
Outlines recommendations, best practices,
configurations, and caveats for implementing a
cell/area zone architecture in an EttF environment.
Chapter 5, “Implementation of Security.”
Describes the security components of the EttF
solution that address the major security concerns of
defending against threat, establishing trust
boundaries and verifying identity, and securing
business communications.
Chapter 6, “Implementation of High
Availability.”
Describes design considerations and best practices
for high availability in the cell/area zone,
manufacturing zone, and the DMZ, as well as
