Moxa Technologies EDS-405A User Manual

 

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.

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