Range of QoS Parameters

host1(config-qos-parameter-define)#instance-interface-type ethernet
In the scheduler hierarchy, IP is above VLANs. If you attempt to configure an
instance-interface type for ip, an error message indicates that you cannot downreference
IP from VLANs.
host1(config-qos-parameter-define)#instance-interface-type ip
% instance-interface-type ip cannot stack above the lowest controlled-interface-type

Subscriber-Interface Types

Subscriber-interface types represent subscriber interfaces to which you can apply QoS
parameters obtained through RADIUS or SRC. You can define up to four
subscriber-interface types for each parameter definition by issuing the
subscriber-interface-type command in QoS Parameter Definition Configuration mode.
The following interface types are supported:
ip
l2tp-session
atm-vc
vlan
QoS clients cannot create a parameter instance for subscriber-interface types that is
above the lowest controlled-interface type of the same family in the interface stack.
If an interface profile contains a QoS parameter instance rule of
max-subscriber-bandwidth 1000000, the system searches the logical interface column,
starting at the top, and associates the parameter instance with the first interface with
the subscriber-interface type that it locates.
A RADIUS administrator can enter multiple QoS parameter name and value pairs when
configuring the RADIUS server with the Juniper Networks VSA [26-82]. This means that
the RADIUS can return multiple instances of the same VSA in a single request. For more
information about Juniper Networks VSA [26-82], see Juniper Networks VSAs.
Subscriber-Interface Type Example
In the following example, you configure a parameter definition with a controlled-interface
type and a subscriber-interface type of IP. These settings enable you to create QoS
parameter VSAs on an IP interface.
host1(config)#qos-parameter-define max-subscriber-bandwidth
host1(config-qos-parameter-define)#controlled-interface-type ip
host1(config-qos-parameter-define)#instance-interface-type ip
host1(config-qos-parameter-define)#subscriber-interface-type ip
You can specify the range of values that the QoS client can enter for a parameter instance
by issuing the range command in QoS Parameter Definition Configuration mode.
In the following example, you specify that a QoS client can enter a value for the parameter
from 512 Kbps to 8 Mbps. The system does not accept values outside of this range.
