Applying Pending Changes
To make your configuration changes active, you must apply them. To apply configuration changes, enter apply at any prompt in the CLI.
Notes
*The apply command is a global command, which means you can enter it at any prompt in the CLI hierarchy.
*All configuration changes take effect immediately when applied, except for starting the Spanning Tree Protocol (STP). To turn STP on or off, you must apply the changes, and save them (see Saving the Configuration).
