Advanced Troubleshooting
One level of switch logging is stored in the two log files located in the /flash directory. There is another
low level debug that can be enabled and used for diagnosing the problems. This debug is known as
“systrace”, meaning system trace. The information in this trace is stored in NVRAM on the CMM, so it is
valid until powered off. Soft reboot of the switch will retain the trace information but powering off the
switch will result in loosing all of the information. This is less CMM intensive so can be used to collect all
the background information about the different tasks running in the switch.
The command to look at the default settings for systrace is
-> debug systrace show
sysTrace is:
- INITIALIZED
- RUNNING
- configured to TRACE CALLERS
- configured to NOT WATCH on stdout
All Applications have their trace level set to level ’info’ (6)
Systrace is set for the level of “info” for all the applications. Any application with trace level other than 6
is displayed in the above command output. Notice that it is initialized by default and is running in the
background. By default it is configured not to display messages on the console. The purpose of systrace is
to track all the system processes called and the caller.
Application log levels can be changed and specific applications can also be set for the logging purposes.
The commands are similar to switch log.

The applications and the log levels are the same as switch log applications. Please refer to the “Section
Switch Logging Commands Overview” section in the “Using Switch Logging” chapter in the appropriate
OmniSwitch Network Configuration Guide.
Systrace can be enabled using the command:
-> debug systrace enable
To look at the systrace log file use the following command:
swnygb02 > debug systrace show log
