User Guidelines
• The parameters
refclassname
and
class-map-name
can not be the same.
• Only one other class may 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.

being configured.
