Storm Control

Overview

The FTOS Storm Control feature allows users to limit or suppress traffic during a traffic storm

(Broadcast/Unknown Unicast Rate Limiting, or Multicast on the C-Series and S-Series).

Support for particular Dell Force10 platforms (C-Series, E-Series, or S-Series) is indicated by the

characters that appear below each command heading:

• C-Series:

• E-Series: e

• S-Series: s

Commands

The Storm Control commands are:

• show storm-control broadcast

• show storm-control multicast

• show storm-control unknown-unicast

• storm-control broadcast (Configuration)

• storm-control broadcast (Interface)

• storm-control multicast (Configuration)

• storm-control multicast (Interface)

• storm-control unknown-unicast (Configuration)

• storm-control unknown-unicast (Interface)

Important Points to Remember

• Interface commands can only be applied on physical interfaces (VLANs and LAG interfaces are

not supported).

• An INTERFACE-level command only support storm control configuration on ingress.

• An INTERFACE-level command overrides any CONFIGURATION-level ingress command for

that physical interface, if both are configured.

• The CONFIGURATION-level storm control commands can be applied at ingress or egress and are

supported on all physical interfaces.

• When storm control is applied on an interface, the percentage of storm control applied is

calculated based on the advertised rate of the line card. It is not based on the speed setting for the

line card.
