7.4  Command privilege configuration 
Command privilege configuration is a flexible tool that allows you to assign baseline user privilege 
level (1–15) to a command set. In future, you may specify privilege level during user creation which will 
define a command set available to them. 
  Levels 1-9 enable all monitoring commands (show …). 
  Levels 10-14 enable all commands except for device reboot, user management and other 
specific commands. 
  Level 15 enables all monitoring commands. 
 
Objective: Transfer all interface information display commands to the privilege level 10 except for 
'show interfaces bridges' command. Transfer 'show interfaces bridges' command to the privilege level 3. 
 
Solution: 
In  configuration  mode,  identify  commands  enabled  for  operation  under  privilege  level  10  and 
privilege level 3.
