Protecting Access to Privileged EXEC Commands
When you set a command to a privilege level, all commands whose syntax is a subset of that command
are also set to that level. For example, if you set the show ip route command to level 15, the show
commands and show ip commands are automatically set to privilege level 15 unless you set them
individually to different levels.
To return to the default privilege for a given command, use the no privilege mode level level command
command in global configuration mode.
The following example shows how to set the configure command to privilege level 14 and how to define
SecretPswd14 as the password users must enter to use level 14 commands:
AP(config)# privilege exec level 14 configure
AP(config)# enable password level 14 SecretPswd14
