This command adds to or removes from the specified class definition the set of match conditions 
defined for another class. The 

 is the name of an existing DiffServ class. The

 is the name of an existing DiffServ class whose match conditions are being 

referenced by the specified class definition. 

Note: there is no 

 option for this match command.

The class types of both <classname> and <refclassname> must be 
identical (i.e., any vs. any, or all vs. all). A class type of acl is not supported by 
this command.

Cannot specify <refclassname> the same as <classname> (i.e., self-
referencing of class name not allowed).

At most one other class may be referenced by a class.

Any attempt to delete the <refclassname> class while still referenced by 
any <classname> shall fail.

The combined match criteria of <classname> and <refclassname> 
must be an allowed combination based on the class type. Any subsequent 
changes to the <refclassname> class match criteria must maintain this 
validity, or the change attempt shall fail.

The total number of class rules formed by the complete reference class chain 
(includes both predecessor and successor classes) must not exceed a platform-
specific maximum.

In some cases, each removal of a refclass rule reduces the maximum number of 
available rules in the class definition by one.
