match class-map
This command adds to the specified class definition the set of match conditions defined for
another class. The <refclassname> is the name of an existing DiffServ class whose match
conditions are being referenced by the specified class definition.
Default none
Format match class-map <refclassname>
Mode
Note the following:
• The parameters <refclassname> and <class-map-name> cannot be the same.
• Only one other class might be referenced by a class.
• Any attempts to delete the <refclassname> class while the class is still referenced by any
<class-map-name> fails.
• The combined match criteria of <class-map-name> 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 fails.
• The total number of class rules formed by the complete reference class chain (including
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.
