and: Specifies the relation between the rules in the class as logic AND. That is, the 
packet that matches all the rules belongs to this class.

or: Specifies the relation between the rules in the class as logic OR. That is, the 
packet that matches any one of the rules belongs to this class.

tcl-name: Class name, a string of characters in the range 1 to 31.
