Enabling and Disabling Storm Control (non-ELS)

 
Note

If your switching device is an EX Series switch and runs Junos OS with support for the Enhanced Layer 2 Software (ELS) configuration style, see Enabling and Disabling Storm Control (ELS).

The factory default configuration enables storm control on all EX Series switch interfaces, with the storm control level set to 80 percent of the combined applicable traffic streams, as follows:

  • On EX2200, EX3200, EX3300, and EX4200 switches—Storm control does not apply to multicast traffic by default. The factory default configuration enables storm control on all interfaces at 80 percent of the available bandwidth used by the combined unknown unicast and broadcast traffic streams.

  • On EX4500 and EX8200 switches—The factory default configuration enables storm control on all interfaces at 80 percent of the combined broadcast, multicast, and unknown unicast streams.

  • On EX6200 switches—Storm control does not apply to multicast traffic by default. The factory default configuration enables storm control on all interfaces at 80 percent of the available bandwidth used by the combined unknown unicast and broadcast traffic streams. Storm control can be disabled for each type of traffic individually.

You can disable storm control for all the applicable types of traffic on all interfaces or on a specified interface, as follows:

  • On all switches—You can selectively disable storm control for broadcast streams, multicast streams, or for unknown unicast streams.

  • On EX8200 switches—You can additionally selectively disable storm control on registered multicast traffic, on unregistered multicast traffic, or on both types of multicast traffic.

  • On EX6200 switches—You can selectively disable storm control for each type of traffic individually.

You can enable storm control for multicast traffic (both registered and unregistered) on all interfaces or on a specific interface. This applies to all switches.

This topic describes:

Disabling Storm Control on Broadcast Traffic

To disable storm control on broadcast traffic:

  • For all interfaces:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface all no-broadcast
  • For an individual interface:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface interface-name no-broadcast

Disabling Storm Control on All Multicast Traffic

To disable storm control on all multicast traffic:

  • For all interfaces:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface all no-multicast
  • For an individual interface:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface interface-name no-multicast

Disabling Storm Control on Registered Multicast Traffic (EX8200 Switches Only)

To disable storm control only on registered multicast traffic (on EX8200 switches only):

  • For all interfaces:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface all no-registered-multicast
  • For an individual interface:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface interface-name no-registered-multicast

Disabling Storm Control on Unregistered Multicast Traffic (EX8200 Switches Only)

To disable storm control only on unregistered multicast traffic (on EX8200 switches only):

  • For all interfaces:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface all no-unregistered-multicast
  • For an individual interface:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface interface-name no-unregistered-multicast

Disabling Storm Control on Unknown Unicast Traffic

To disable storm control on unknown unicast traffic:

  • For all interfaces:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface all no-unknown-unicast
  • For an individual interface:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface interface-name no-unknown-unicast

Enabling Storm Control on Multicast Traffic

To enable storm control on multicast traffic:

  • For all interfaces:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface all multicast
  • For an individual interface:

    [edit ethernet-switching-options]

    user@switch# set storm-control interface interface-name multicast
