Description
Use the debugging command to enable system debugging.
Use the undo debugging command to disable system debugging.
By default, all debugging is disabled for the system.
Ethernet switches provide various debugging functions for technical support specialists
and senior maintenance personnel to do network fault diagnostics.
Enabling debugging will generate a great deal of debugging information and thus will
affect the efficiency of the system, especially after enabling all debugging through the
debugging all command, the system may collapse. Therefore, it is recommended not
to use the debugging all command. The undo debugging all command brings great
convenience for you to disable all debugging at a time instead of disabling them one by
one.
Related command: display debugging.
