Version 34.1.1 extends flood rate-limiting to support bandwidth-based rate limiting in addition to packet-count limiting, enabling byte-rate control for flooded traffic.
Overview: Flood rate-limiting accepts bandwidth rate limits in addition to packet-per-second (pps) limits. Specify the rate in Kbps, Mbps, or Gbps, with an optional burst size, for broadcast, multicast, and unknown destination MAC traffic.
Configure flood rate-limit in bandwidth mode:
configure ports [port_list | port_group] rate-limit flood [broadcast | multicast | unknown-destmac] [no-limit | pps | flood_bandwidth_rate [Kbps | Mbps | Gbps] {flood-burst-size burst_size [Kb | Mb]}]
Example: The following command limits broadcast flood traffic on port 1 to 200 Mbps:
configure ports 1 rate-limit flood broadcast 200000 Kbps flood-burst-size 100 Kb out-actions log disable-port

The following example shows the flood rate-limit settings in the output for port 1:
