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. The PT-7828 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.

Broadcast Storm Protection

Setting

Description

Factory Default

Enable/Disable

This enables or disables Broadcast Storm Protection for
unknown broadcast packet globally.
