no command operator

You can use the no operator in a command to negate a configuration. Based on the functionality of the command, you can perform negations, such as disable, delete, remove, or reset to the default configuration. For more information about the no operator for each command, see VOSS Command References.

Use the ? command completion along with the no keyword to view the list of commands that support the no operator in each configuration mode. For more information, see Command Completion.
