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. The maximum number of interfaces on which BUM Rate Limit can be configured is 512.
RUCKUS ICX devices support byte-based and packet-based rate limiting.
For ICX 8100 and ICX 8200 devices, the packets-per-second rate limiting uses increments of 125.
