Storm Control

Storm Control
Use the Port Configuration > Storm Control page to configure broadcast,
multicast, and unknown unicast storm control thresholds. Traffic storms may occur
when a device on your network is malfunctioning, or if application programs are
not well designed or properly configured. If there is too much traffic on your
network, performance can be severely degraded or everything can come to
complete halt.
You can protect your network from traffic storms by setting a threshold for
broadcast, multicast or unknown unicast traffic. Any packets exceeding the
specified threshold will then be dropped.
Usage Guidelines
Storm Control for broadcast, unknown multicast, and unknown unicast traffic is

disabled by default.
When traffic exceeds the threshold specified for broadcast and multicast or

unknown unicast traffic, packets exceeding the threshold are dropped until the
rate falls back down beneath the threshold.
Using both rate limiting (Port Speed Limit) and storm control on the same

interface may lead to unexpected results. It is therefore not advisable to use
both of these features on the same interface.
Parameters
These parameters are displayed:
Port — Displays a list of ports to select. Trunk ports cannot be selected.

Broadcast — Specifies storm control for broadcast traffic.

Unknown Unicast — Specifies storm control for unknown unicast traffic.

Unknown Multicast — Specifies storm control for unknown multicast traffic.

State — Enables or disables storm control. (Default: Disabled for broadcast,

unknown multicast, and unknown unicast)
Speed — Threshold level in 1000 bits per second.

(Range: 1-1000000 kbps; Default: 0, disabled)
