Configuring multicast traffic engineering

Using the multicast traffic engineering feature, you can limit the amount of multicast traffic that

passes through a packet processor. This command is configured on an individual port but applies

to all ports connected to the same packet processor.

If a user configures any one port between 1-12 (or 13 - 24) with a 'qos multicast best-effort rate of

1Mbps', no more then 1Mbps of multicast traffic will be forwarded at one time on ports 1-12 or

Starting release 02.5.00, data-plane multicast traffic is rate-limited to 1.8 Gbps per packet

Using the qos multicast best-effort rate command affects data-plane (non-control protocol)

multicast, broadcast and unknown unicast flooded traffic, that prior to inclusion of the command

there was a potential for this traffic to starve other traffic from accessing an egress queue. The

limiting on a per traffic manager basis to 1.8 Gbps was best for the majority of environments. Some

high intensity multicast environments may need to increase this value to better match their network

requirements.
