Using Diagnostic Commands

This chapter contains the following sections:

Using debug commands

This section describes how to use debug commands to monitor and troubleshoot Brocade FCX,
Brocade ICX, and Brocade TurboIron switch configurations. The debug commands are accessible
from the Privileged EXEC mode in the IronWare command line interface (CLI). Most of the debug
commands can be configured to send output to a specified destination.
When enabled, the debug commands can noticeably affect system performance. Many debug
commands are specifically designed to be used in conjunction with calls to Brocade technical
support. If you report a problem, the support engineer may ask you to execute one or more of the
debug commands described in this guide.
ATTENTION
Some debug commands report information about internal hardware settings and registers, which is
relevant primarily to the Brocade engineering staff. These commands are not described in this
document.

Brief and detail debug options

When enabled, many debug commands can significantly impact system performance. Many debug
commands provide options for brief or detailed reporting. Generating detailed output places an
additional burden on system performance, and in many cases the results may be more difficult to
interpret than output generated using the brief option. To conserve performance and prevent
system disruption, use the brief option whenever possible.
