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.
NOTE
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
(13-24).
Starting release 02.5.00, data-plane multicast traffic is rate-limited to 1.8 Gbps per packet
processor.
NOTE
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.
