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.
