Chapter 12 Configuring Quality of Service on the ML-Series Card
Configuring Multicast Priority Queuing QoS
Multicast Priority Queuing QoS Restrictions
The following restrictions apply to multicast priority queuing QoS:
•
The bandwidth allocation and utilization configured for multicast priority queuing traffic is global
and applies to all the ports on the ML-Series card, both POS and Fast Ethernet, regardless of whether
these ports carry multicast priority queuing traffic. The rate of traffic can be reduced for all ports on
the ML-Series card when this feature is configured. Default multicast traffic uses bandwidth only
on the ports where it egresses, not globally like multicast priority queuing.
•
Multicast priority queuing QoS is supported only for Layer 2 bridging.
•
The ML-Series card supports a maximum of two multicast priority queuing classes.
•
Unlike the rest of the ML-Series card QoS, multicast priority queuing QoS is not part of the
Cisco IOS MQC.
•
Priority-mcast bandwidth allocation is per port.
Configuring Multicast Priority Queuing QoS
To configure a priority class for multicast traffic, use the global configuration cos priority-mcast
command defined in Table 12-5.
