46.Packet Storm Commands
A packet storm is a phenomenon where packets overflow on the
network. It occurs when a large amount of broadcast or multicast data
is sent simultaneously or a network device fails. A packet storm
decreases network efficiency, interfering with normal communications.
This Switching Hub allows you to monitor and control a packet storm
on a specified port with the following methods.

drop: Discard exceeded packets if the number of packets exceeds a set threshold.
 shutdown: Stop transferring packets if the number of packets exceeds a set
threshold. If a packet storm does not stop within a specified time, the port is kept
isolated until it is recovered manually.
