Configuring a Parameter Definition to Calculate Hierarchical Instances

246
You can specify only a subset of the instance-interface types that are supported for
non-hierarchical parameters. The following output lists the instance-interface types
that are supported:
host1(config)#qos-parameter-define hierarchical-parameter hierarchical
host1(config-qos-parameter-define)#instance-interface-type ?
atm-vc ATM Virtual Circuit (VC)
ip IP interface
ipv6 IP version 6 interface
l2tp-session L2tp session interface
vlan VLAN subinterface
You can specify only one instance-interface type per hierarchical parameter. For
example:
host1(config)#qos-parameter-define hierarchical-parameter hierarchical
host1(config-qos-parameter-define)#instance-interface-type ip
host1(config-qos-parameter-define)#instance-interface-type vlan
% only one instance-interface-type can be specified for a hierarchical parameter
Hierarchical instance-interface types cannot stack above the highest
controlled-interface type. For example:
host1(config)#qos-parameter-define hierarchical-parameter hierarchical
host1(config-qos-parameter-define)#controlled-interface-type ip
host1(config-qos-parameter-define)#instance-interface-type vlan
% hierarchical instance-interface-type vlan cannot stack above
controlled-interface-type ip
In contrast, a non-hierarchical instance-interface type cannot stack above the lowest
controlled-interface type (vlan). For example:
host1(config)#qos-parameter-define non-hierarchical-parameter
host1(config-qos-parameter-define)#controlled-interface-type vlan
host1(config-qos-parameter-define)#instance-interface-type ip
% instance-interface-type ip cannot stack above the lowest controlled-interface-type
You must specify a subscriber-interface type that is identical to the instanceinterface
type that you specified.
Configuring a Parameter Definition to Calculate Hierarchical Instances on page 246
You can configure hierarchical parameters for applications where you want the system
to add instances associated with child interfaces and associate the sum with a parent
interface.
Hierarchical parameters have explicit instances that are associated with the logical
interfaces of instance-interface types, as well as implicit instances that are associated
with the logical interfaces of controlled-interface types. The system computes the values
of an implicit instance as the sum of the values of the explicit instances stacked above
the implicit instance.
