The following example changes the previously created rule (index number 155) so that the 
		  username command is replaced by the 
		  role command. 
		
 
	 
 
	 -  
		   In privileged EXEC mode, use the 
			 configure terminal command to enter global configuration mode. 
		   
		  
 
			 device# configure terminal
 
		    
		 -  
		   Enter the 
			 rule command, specifying an existing rule (index 155) and the role; and changing the 
			 command attribute to the 
			 role command. 
		   
		  
 
			 device(config)# rule 155 role SecAdminUser command role
 
		    
		  After changing rule 155, "SecAdminUser" users can execute the 
			 role command, but not the 
			 username command.
