Using the Debug Interface
Using the debug all Command: Warning
To enable all system diagnostics, you can enter the debug all command in privileged EXEC mode at the
command line.
Caution Because debugging output takes priority over other network traffic, and because the debug all
command generates more output than any other debug command, it can severely diminish switch
router performance or render the switch router unusable. Use more specific debug commands.
The no debug all command turns off all diagnostic output. Using this command is a convenient way to
ensure that you have not accidentally left any debug commands turned on.
Generating debug Command Output
Enabling a debug command can result in output similar to the following example for the debug lane
client all command:
Switch# debug lane client all
