How this document is organized
This document is organized to help you find the information that you want as quickly and easily as
possible.
This document contains the following components:
•Chapter 1, “About Fabric Watch,” provides an introduction to Fabric Watch and the benefits of
its use. It also defines concepts that are useful in Fabric Watch configuration.
•Chapter 2, “Fabric Watch Best Practices” describes some of the modifications Fabric Watch
users should consider when configuring their implementation.
•Chapter 3, “Fabric Watch components,” describes the components (class, area, and element)
associated with every monitored behavior.
•Chapter 4, “Fabric Watch threshold concepts,” explains the concept of high and low thresholds
and buffer values and provides examples of various threshold settings.
•Chapter 5, “Fabric Watch activation,” describes the Fabric Watch requirements, provides an
overview of the interfaces, and explains the methods of accessing Fabric Watch through each
interface.
•Chapter 6, “Fabric Watch basic configurations,” describes how to configure thresholds using
either the fwConfigure command or the portThConfig command and how to configure
notification alerts and events.
•Chapter 7, “Port fencing,” describes how to configure the optional port fencing feature.
•Chapter 8, “Advanced configuration” describes how to configure advanced configuration
options and lists the advanced configuration options.
•Chapter 9, “Fabric Watch Reports,” describes the reports available through Fabric Watch and
the methods of accessing each.
•Chapter 10, “Switch and FRU configuration” lists the switch status policy factors that affect the
health of the switch and describes how to set and view status policies. It also details how to
configure FRUs.

•Chapter 11, “System monitoring” describes how to configure system memory and CPU values
using the sysMonitor command.
•Appendix A, “Fabric Watch commands” lists Fabric Watch commands. Many of these
commands are used in advanced configuration tasks.
•Appendix B, “Fabric Watch default settings” lists the default settings for all the classes which
you can use to rapidly deploy and monitor your fabric.
•Appendix C, “portThConfig examples,” provides examples that can be used when configuring
thresholds using the portThConfig command.
•Appendix D, “Port fencing types” describes the set of port fencing types that are available in
M-EOS and Fabric OS v6.3.0.
•The index points you to the exact pages on which specific information is located.

What’s new in this document
This document contains information that was available at the time the product was released. Any
information that becomes available after the release of this document is captured in the Release
Notes.
New information
The following Information was added:
•Port threshold configuration using the portThConfig command. This does not replace the
fwConfigure command but, rather, is an alternate method of configuring port thresholds.
•Port fencing information using the portFencing command.
•System monitoring information using the sysMonitor command.
•Added State Change, Packet Loss, and Utilization areas to the VE_Port class.
Changed information
The following information was changed:
•High, low, and buffer threshold settings for the following classes and areas:
•Environment class, temperature area.
•Port class, Class 3 Discard area, Invalid Transmission Word (ITW) area, Link Failure Count
area, Loss of Synchronization Count area, and State Changes area.
•“Trunk Utilization” is now “Utilization.”
•E-Port class, Class 3 Discard area, Link Failure Count area, Loss of Synchronization Count
area, State Changes area.
•FOP_Port class, Class 3 Discard area, Loss of Synchronization Count area, State Changes
area, Invalid Transmission Word (ITW) area, Link Failure Count area, Trunk Utilization Area.
•Resource class, Flash area.
•“F_Port” is now referred to as “FOP_Port.”
Removed information
The following information was removed:
•Environment class, fan area (no longer supported).
•Performance Monitor, AL_PA area (this area still displays using the fwConfigure command, but
it is no longer supported).

Document conventions
This section describes text formatting conventions and important notices formats.
Text Formatting
The narrative-text formatting conventions that are used in this document are as follows:
bold text Identifies command names
Identifies the names of user-manipulated GUI elements
Identifies keywords and operands
Identifies text to enter at the GUI or CLI
italic text Provides emphasis
Identifies variables
Identifies paths and Internet addresses
Identifies document titles
code text Identifies CLI output
Identifies syntax examples
For readability, command names in the narrative portions of this guide are presented in mixed
lettercase: for example, switchShow. In actual examples, command lettercase is often all
lowercase. Otherwise, this manual specifically notes those cases in which a command is case
sensitive.
Notes, cautions, and warnings
The following notices and statements are used in this manual. They are listed below in order of
increasing severity of potential hazards.
NOTE
A note provides a tip, guidance or advice, emphasizes important information, or provides a reference
to related information.
ATTENTION
An Attention statement indicates potential damage to hardware or data.
CAUTION
A Caution statement alerts you to situations that can be potentially hazardous to you or cause
damage to hardware, firmware, software, or data.
DANGER
A Danger statement indicates conditions or situations that can be potentially lethal or extremely
hazardous to you. Safety labels are also attached directly to products to warn of these conditions
or situations.
