Storm Control

Overview

After you configure broadcast/unknown unicast/unknown multicast storm control on an interface, if
the broadcast/unknown unicast/unknown multicast traffic exceeds the specified threshold, the
system discards the excessive traffic.

On a Layer 2 Ethernet interface, you can also configure traffic thresholds to suppress traffic storms.
Traffic threshold control suppresses traffic through software, which might affect device performance.
Storm control uses the chip to suppress traffic and has less impact on the device performance than
traffic threshold control.

After packets of a protocol are added to the storm suppression and storm control allowlist, storm
suppression and storm control do not take effect on packets of the protocol.

Configuring storm control

1.

From the navigation pane, select

QoS Settings

>

Storm Control

.

2.

Select a traffic type from the

Storm Type

list.

3.

Select the target ports.

4.

Enable or disable storm control. By default, storm control is disabled.

5.

Set the suppression threshold in the Speed field.

6.

Click

Submit
