By default, a switch has four user levels, ranging from 0 to 3. To increase the level of a command in a view, run the command-privilege level command.
For example, a level 3 user can use the delete or format command in the user view to delete the startup file or format the storage device that saves the startup file. To increase the level of the delete and format commands, create a user account of a higher level and run the following commands:

•  command-privilege level 15 view shell delete

            Only level 15 users can use the commands starting with delete in the user view (shell).

•  command-privilege level 15 view shell format

            Only level 15 users can use the commands starting with format in the user view (shell).
