Use the display current-configuration command to display the currently running
configuration parameters of the switch.
Running configuration parameters adopting the default values will not be displayed.
If you want to verify the configurations after finishing a set of configurations, you can
use the display current-configuration command to display the running parameters.
Although you have configured some parameters, they are not displayed if the related
functions are not effective.
When there is plenty of configuration information, you can use a regular expression to
filter the output information.
