A given class definition can contain a maximum of one reference to another class. You can
combine the reference with other match criteria. The referenced class is truly a reference and not a
copy since additions to a referenced class affect all classes that reference it. Changes to any class
definition currently referenced by any other class must result in valid class definitions for all
derived classes, otherwise the switch rejects the change. You can remove a class reference from a
class definition.
The only way to remove an individual match criterion from an existing class definition is to delete
the class and re-create it.
Note: The mark possibilities for policing include CoS, IP DSCP, and IP Precedence.
While the latter two are only meaningful for IP packet types, CoS marking is
allowed for both IP and non-IP packets, since it updates the 802.1p user priority
field contained in the VLAN tag of the layer 2 packet header.
