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 prevents 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
Please note that two types of bandwidth management settings are available, depending on the specific model
of switch.
