Configuring a Parameter Definition for IP Multicast Bandwidth Adjustment

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

Configure traffic classes.


                  
                     host1(config)#traffic-class voice 
                     
                     host1(config-traffic-class)#exit 
                     
                     host1(config)#traffic-class best-effort 
                     
                     host1(config-traffic-class)#exit

Create a parameter definition.

Configure the QoS parameter name and the application.
host1(config)#qos-parameter-define ipm application ip-multicast hierarchical
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

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.
