Rate Limiting

In general, one host should not be allowed to occupy unlimited bandwidth, particularly when the device

malfunctions. For example, so-called “broadcast storms” could be caused by an incorrectly configured topology,

or a malfunctioning device. Moxa industrial Ethernet switches not only prevent broadcast storms, but can also

be configured to a different ingress rate for all packets, giving administrators full control of their limited

bandwidth to prevent undesirable effects caused by unpredictable faults.

Traffic Rate Limiting Settings

There are four types of bandwidth management settings, depending on which model of switch you are using.

Type Model

Type 1 EDS-510E

Type 2 EDS-G508E, EDS-G512E-4GSFP, EDS-G516E-4GSFP, EDS-G512E-8PoE

Type 1

For Type 1, the Control Mode setting on the Rate Limiting page can be set to Normal or Port Disable.

Control Mode

Setting Description Factory Default

Normal Set the max. ingress rate limit for different packet types Normal

Port Disable When the ingress multicast and broadcast packets exceed the

ingress rate limit, the port will be disabled for a certain period.

During this period, all packets from this port will be discarded.
