enable — command
With no arguments, this command takes an interactive session from user EXEC
mode to privileged EXEC mode. If the
level argument is present, it can be used to enter any of 16 levels, 0 through 15. Level 0 is the normal user mode (user EXEC mode) and 15 is the privileged user mode (privileged EXEC mode). See the
privilege command in Chapter 4 for more information on setting the level values.
