3. Object, Structure and Commands

Bayonet Object is the base object for all the essential objects used in Bayonet System. They are the basic components of managing and constructing networks.

Here are the bayonet objects used mainly in Bayonet System.

Check out the GUI operations related to these objects in the chapter, GUI Help.
