ProSafe M4100 and M7100 Managed Switches The following rules apply when you create a DiffServ class: • Each class can contain a maximum of one referenced (nested) class • Class definitions do not support hierarchical service policies 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, because 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. diffserv This command sets the DiffServ operational mode to active.
