A switch can be configured to block massive transmission of broadcast packets being forwarded to every port on the same VLAN. This is also known as broadcast storm protection.
Failure to block broadcast storm packets can cause a delay or halt to other data. Some switches allow you to select a storm control rate for each port, others assign a predetermined storm control rate for all ports on the switch.
