After the QoS profile is attached to the interface, the IP multicast bandwidth
adjustment application begins to adjust rates based on IGMP joins and leaves received
on that interface.

Configuring a Parameter Definition for IP Multicast Bandwidth Adjustment
host1(config)#traffic-class best-effort
host1(config-traffic-class)#exit
Create a parameter definition.
a. Configure the QoS parameter name and the application.
host1(config)#qos-parameter-define ipm application ip-multicast hierarchical
b. Configure a controlled-interface type.
host1(config-qos-parameter-define)#controlled-interface-type vlan
host1(config-qos-parameter-define)#exit
Create a parameter instance that globally defines the value of the IP multicast
adjustment as 0.
host1(config)#qos-parameter ipm 0
Reference the parameter within a scheduler profile parameter expression.
host1(config)#scheduler-profile vlan-subscriber
host1(config-scheduler-profile)#shared-shaping-rate 1000000 - ipm burst 50
milliseconds auto
host1(config-scheduler-profile)#exit
Add the scheduler profile to a QoS profile.
host1(config)#qos-profile vlan-subscriber
host1(config-qos-profile)#vlan queue traffic-class best-effort
host1(config-qos-profile)#vlan queue traffic-class voice scheduler-profile 192k
host1(config-qos-profile)#vlan node scheduler-profile vlan-subscriber
host1(config-qos-profile)#exit
Attach the parameter definition to a logical interface.
host1(config)#interface gigabitEthernet 7/0
host1(config-if)#encapsulation vlan
host1(config-if)#exit
host1(config)#interface gigabitEthernet 7/0.1
host1(config-if)#vlan id 200
host1(config-if)#qos-profile vlan-subscriber
host1(config-if)#ip address 1.1.1.1 255.255.255.0
