Configuring multicast traffic engineering
18
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.
To limit the multicast traffic through the packet processor that includes port 1/1 to 10 Mbps, use
the following command.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# qos multicast best-effort rate 10000
Syntax: qos multicast best-effort rate <rate>
The <rate> variable defines the bandwidth of multicast traffic that is allowed to pass through the
packet processor that include the port this command is configured on. On a 24-port x 1 Gbps
Interface module, a qos multicast command applied to any of the ports numbered 1 to 12 will
apply to all of these ports. Any command applied to ports numbered 13 to 24 will apply to these
ports.
This variable is configured in Kbps.
The minimum configurable rate is 10 Mbps.
