Introduction

This guide describes many common diagnostic processes for the Brocade FastIron devices. Each

chapter contains diagnostic information about a specific segment of your network configuration.

Supported Hardware

•FastIron X Series devices (chassis models):

•Brocade FastIron SX 800

•FastIron SX 1600

•Brocade FCX Series (Brocade FCX) Stackable Switch

•Brocade ICX 6610 (ICX 6610) Stackable Switch

•Brocade ICX 6430 Series (ICX 6430)

•Brocade ICX 6450 Series (ICX 6450)

•Brocade ICX 6650 Series (ICX 6650)

•Brocade TurboIron 24X Series

For information about the specific models and modules supported in a product family, refer to the

hardware installation guide for that product family. “Related publications” on page x lists the

hardware installation guides and software configuration guides.

NOTE

The Brocade ICX 6430-C switch supports the same feature set as the Brocade ICX 6430 switch

unless otherwise noted.

viii Brocade FastIron, FCX, ICX, and TurboIron Diagnostic Reference

53-1002965-01

NOTE

The Brocade ICX 6450-C12-PD switch supports the same feature set as the Brocade ICX 6450

switch unless otherwise noted.

NOTE

Some debug commands report information about internal hardware settings and registers that is

relevant primarily to the Brocade engineering staff. Consequently, this information is not described

in this document.

Unsupported features

Features that are not documented in “Related publications” on page x are not supported.

Audience

This document is designed for network engineers with a working knowledge of Layer 2 and Layer 3

switching and routing.

If you are using a Brocade Layer 3 switch, you should be familiar with the following protocols if

applicable to your network – IP, RIP, OSPF, BGP, ISIS, IGMP, PIM, DVMRP, and VRRP.

manual to troubleshoot Brocade products, you assume all risk as to the quality and performance of

the debug procedures. Brocade assumes no liability for any damages, including general, special,

incidental, or consequential damages arising from the use of the procedures in this manual

(including, but not limited to any loss of profit or savings, loss of data, or failure to successfully

troubleshoot network problems).

Debug information may be changed or updated without notice. You are responsible for obtaining

newer versions of this manual when they are made available. The procedures in this document are

not intended as a substitute for the expertise of qualified technicians.

Enabling debug commands can seriously degrade system performance. Debug commands are

generally intended for use when troubleshooting specific problems while working with qualified

service technicians, or in conjunction with calls to Brocade Technical Support. Whenever possible,
