Rate limiting broadcast, unknown unicast, and multicast traffic
RUCKUS ICX devices can forward all flooded traffic at wire speed within a VLAN. However,
some third party networking devices cannot handle high rates of broadcast, unknown
unicast, and multicast (BUM) traffic.
If high rates of traffic are being received by the device on a given port of that VLAN, you can limit the number of BUM packets or bytes received each second on that port. This can help to control the number of such packets or bytes that are flooded on the VLAN to other devices.
RUCKUS ICX devices support byte-based and packet-based rate limiting.
