Configuring a Parameter Definition to Calculate Hierarchical Instances
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

Configuring a Parameter Definition to Calculate Hierarchical Instances
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.
