Storm Control Overview

FTOS Storm Control is a preventative measure against unexpectedly high rates of broadcast or multicast 
packets; these traffic bursts are called 

storms

. If the rate of these packets on ingress or egress exceeds a 

user-defined threshold, FTOS, when configured, can suppress forwarding for these packets until the packet 
rate falls back to the configured limit.

Situations that Can Lead to Packet Storms

•

Layer 2 Broadcasts—

A switch might not have an entry in its MAC address table that matches a 

packet’s destination MAC. In this case, the switch floods the packet on the VLAN. These packets are 
called unknown-packets; they cause unnecessary extra traffic and can reduce network performance.

•

Layer 3 Broadcast Packets

—There are two types of Layer 3 broadcast packets: the all-hosts 

broadcast, the IP address of which is 255.255.255.255, and the subnet broadcast address, the address of 
which has the host portion of the address set to all ones; for example, 10.11.1.255/24 is the broadcast 
address for the 10.11.1.0 network. Some protocols utilize broadcasts more than others and so storm 
control might be useful to prevent congestion.

•

Multicast Packets—

Multicast packets are packets that use a special range of MAC and IP addresses 

to send packets to a group of hosts, rather than a single host. Some multicast applications can cause 
excessive bandwidth consumption, and storm control can be used (in conjunction with IGMP 
Snooping) to limit multicast traffic.
