Guidelines for Configuring IP Multicast Adjustment for QoS
When you specify the IP multicast bandwidth adjustment application, the following
considerations apply:
■
You must specify a controlled-interface type.
■
You cannot specify any instance-interface types or subscriber-interface types.
By default, the system assigns a default instance-interface type of ip.
■
When you specify the IP multicast bandwidth adjustment application, the
parameter definition is hierarchical. You must specify the
hierarchical keyword
with the application keyword.
■
The system prevents you from defining more than one parameter definition with
the
ip-multicast application specified. For example:
host1(config)# qos-parameter-define vpShaper application ip-multicast hierarchical
host1(config-qos-parameter-define)# controlled-interface-type ip
host1(config-qos-parameter-define)# exit
host1(config)# qos-parameter-define bar application ip-multicast hierarchical
% there cannot be more than one parameter defined with this property
■
Parameter instances associated with the IP multicast bandwidth adjustment
application are not stored in non-volatile storage (NVS). (Parameter definitions
are stored in NVS.) Because the application is activated based on IGMP joins and
leaves received on an interface, the system removes the instances when you
turn off or reset the router, then re-creates it based on new messages received
on an interface.

Configuring a Parameter Definition for IP Multicast Bandwidth Adjustment
Before you configure a parameter definition for IP multicast bandwidth:
■
Define a multicast bandwidth map and the QoS adjustment for a virtual router.

To associate a parameter instance with the IP multicast bandwidth adjustment
application:

Configure traffic classes.
