instances at VLAN, SVLAN, and Ethernet interfaces by configuring instance-interface
types of vlan, svlan, and ethernet.
host1(config)# qos-parameter-define max-subscriber-bandwidth
host1(config-qos-parameter-define)# controlled-interface-type vlan
host1(config-qos-parameter-define)# instance-interface-type vlan
host1(config-qos-parameter-define)# instance-interface-type svlan
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
