If the configuration is incorrect, run the undo command to clear the configuration or enter a new value to overwrite the existing one.

But when you need to clear them in batches or in the entire system, these two rarely used methods can help you.

1.Clear the port configuration.

Warning: All configurations of the interface will be cleared, and its state will
 be shutdown. Continue? [Y/N] :y...
Info: Total execute 2 command(s), 2 successful, 0 failed. 

Note:After the configuration of the port is cleared, the port is disabled. You can run the following command to enable the port again.

2.Clear all configurations of the switch.
