text: A well-chosen name serves both as a label for an object and as a tool for tracking and 
  managing the object. Choosing a meaningful name is important if you decide to use 
  configuration backup and restore. 
  
  When you choose a name for an object, apply the following naming rules: 
  
  (cid:2) Names must begin with a letter. 
  
  **Important**: Do not start names by using an underscore (_) character, even though it is 
  possible. The use of the underscore as the first character of a name is a reserved 
  naming convention that is used by the system configuration restore process.
