Configuring Multicast QoS Adjustment

When the router uses multicast OIF mapping, any multicast streams that a subscriber
receives bypass any configured QoS treatment for that subscriber interface. The
Multicast QoS adjust feature provides a way in which the router can account for this
multicast traffic.
NOTE: For additional information about how to configure OIF mapping, see
"Configuring Group Outgoing Interface Mapping" on page 53.
The following sections provide two possible configuration cases for using multicast
QoS adjustment.
NOTE: For additional information about QoS adjustment, see IP Multicast Bandwidth
Adjustment for QoS Overview .

Multicast OIF Mapping Case

Multicast OIF mapping enables the router to decrease the inefficiencies associated
with replicating streams of multicast traffic. Using OIF maps, IGMP joins that the
router receives on a subscriber interface can be mapped to a special interface for
Use to configure a priority value for the <S, G> data stream on a physical port.
Dynamic multicast admission control enables only prioritized groups to join the
interface after the configured priority limit is reached on the physical port. The
system records the priority when a new <S, G> entry is created.
Example
host1(config-route-map)#set priority 100
Use the no version to remove the priority value.
See set priority.
Use to set a multicast bandwidth for QoS adjustment.
Use the adaptive keyword to define the bandwidth as adaptive (automatically
sensed).
Example
host1(config-route-map)#set qos-bandwidth 10000000
Use the no version to remove the set clause from a route map.
See set qos-bandwidth.
