3.9 Using Bandwidth Management

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. Weidmüller 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.

3.9.1 Configuring Bandwidth Management

There are two two types of bandwidth management settings available, depending on the specific

model of switch.
