Using Rate Limiting

Single devices should not occupy unlimited bandwidth, especially when the device malfunctions. The most well-know problem is the broadcast storm caused by an incorrect topology or malfunctioning device. The EDS-508 series not only prevents broadcast storms, but can also configure the ingress/egress rate of unicast/multicast/broadcast packets, thus helping the administrator control fully the limited bandwidth, and prevent unpredictable faults before they occur.
