Troubleshooting Commands
If you encounter problems when using your switch, ExtremeWare troubleshooting commands can help
identify and solve the problem. Use these commands only under the guidance of Extreme Networks
technical personnel.
You can contact Extreme Networks technical support at (800) 998-2408 or (408) 579-2826.
The Event Management System (EMS), introduced in ExtremeWare 7.1.0, provides enhanced features to
filter and capture information generated on a switch. The various systems in ExtremeWare are being
converted to EMS components. As a system is converted, the corresponding debug trace command is no
longer available. Details of using EMS are discussed in the ExtremeWare User Guide, in the chapter
"Status Monitoring and Statistics", and the commands used for EMS are detailed in this document in
Chapter 10, "Commands for Status Monitoring and Statistics".
Until all the systems in ExtremeWare are converted, you may need to use a mix of EMS and debug
trace commands under the guidance of Extreme Networks technical personnel.
Included in this chapter, as well as in Chapter 10, are the EMS commands to enable and disable debug
mode for EMS components.
The debug trace commands require the CPU; therefore, if CPU utilization is high, use these commands
sparingly. Disable any external syslog before you configure a debug trace, because the debug trace
utility can send large amounts of information to the syslog, and if your syslog is external, that
information travels over your network. Alternatively, you can configure a filter to select only the most
necessary information.
Configure a debug trace at lower levels first, and look for obvious problems. Higher levels typically
record so much information that they record enough information within a few seconds.
