Using Rate Limiting
A single device should not be allowed to occupy unlimited bandwidth, especially when the device
malfunctions. For example, broadcast storms could be caused by an incorrect topology or
malfunctioning device. The IE-SW-VL08M devices not only prevents broadcast storms, but can
also configure the ingress rate of unicast/multicast/broadcast packets, giving administrators full
control of the limited bandwidth, and preventing unpredictable faults before they occur.
