490 BigIron RX Series Configuration Guide53-1001986-01Configuring multicast traffic engineering18Syntax: show qos schedulerConfiguring multicast traffic engineeringUsing the multicast traffic engineering feature, you can limit the amount of multicast traffic thatpasses through a packet processor. This command is configured on an individual port but appliesto all ports connected to the same packet processor.NOTEIf a user configures any one port between 1-12 (or 13 - 24) with a 'qos multicast best-effort rate of1Mbps', 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 packetprocessor.NOTEUsing 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 commandthere was a potential for this traffic to starve other traffic from accessing an egress queue. Thelimiting on a per traffic manager basis to 1.8 Gbps was best for the majority of environments. Somehigh intensity multicast environments may need to increase this value to better match their networkrequirements.BigIron RX#show qos schedulerPort | Scheduler Type Prio0 Prio1 Prio2 Prio3| (Rates where specified are in Kbps)-------+-------------------------------------+---------+---------+---------13/1 | strict13/2 | enhanced-strict Rate 100000 200000 300000 Remaining13/3 | min-rate Rate 102400 204800 307200 40960013/4 | strict13/5 | strict13/6 | max-rate Rate 400000 400000 800000 1000000013/7 | destination-weighted Weight 15 25 25 3513/8 | strict13/9 | source-weighted Weight 5 15 35 4513/10 | strict13/11 | strict13/12 | strict13/13 | strict13/14 | strict13/15 | strict13/16 | strict13/17 | strict13/18 | strict13/19 | strict13/20 | strict13/21 | strict13/22 | strict13/23 | strict13/24 | strict
