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 EDS-408A/405A series 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.

Configuring Rate Limiting

NOTE: The user interface for the EDS-408A shows 8 ports.
