About This DocumentThis manual describes troubleshooting and diagnostic commands available in the IronWarecommand line interface (CLI) for Brocade NetIron XMR series and Brocade MLX series devices.NOTESome troubleshooting commands report information about internal hardware settings and registersthat is relevant primarily to the Brocade engineering staff. Consequently, this information is notdescribed in this document.DisclaimerThis manual is provided without any warranty of any kind, expressed or implied. When using thismanual to troubleshoot Brocade products, you assume all risk as to the quality and performance ofthe diagnostic procedures. Brocade assumes no liability for any damages, including general,special, incidental, or consequential damages arising from the use of the diagnostic procedures inthis manual (including, but not limited to any loss of profit or savings, loss of data, or failure tosuccessfully troubleshoot network problems).Diagnostic information may be changed or updated without notice. You are responsible forobtaining newer versions of this manual when they are made available. The procedures in thisdocument are not intended as a substitute for the expertise of qualified technicians.Enabling diagnostic commands can seriously degrade system performance. Diagnostic commandsare generally intended for use when troubleshooting specific problems while working with qualifiedservice technicians, or in conjunction with calls to Brocade Technical Support. Whenever possible,troubleshoot your system during periods of low network traffic and user activity to preserve systemperformance.If you have any questions regarding this Disclaimer please contact us at support@brocade.com.How to use this guideThis guide describes many common diagnostic processes for the Brocade NetIron XMR andBrocade MLX series devices. Each chapter contains diagnostic information about a specificsegment of your network configuration. Each topic consists of the following sections, wherepossible, and when the information is applicable:• A brief description of the topic• Show commands related to the topic• Debug commands related to the topic• Configuration notes for the topic• Common diagnostic scenariosBrocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02xi
