Configuring Traffic Suppression over a VSI

Configuring Traffic Suppression over a VSI

This section describes how to configure traffic suppression in a specified virtual switch instance (VSI) to prevent a large volume of traffic from overloading the network.

Applicable Environment

On an Ethernet network, to manage user traffic, user bandwidth must be assigned. In addition, to ensure secure transmission of unicast traffic and proper bandwidth utilization, unknown unicast, multicast, and broadcast traffic must be suppressed.

On most networks, the unicast traffic volume is far higher than the broadcast traffic volume. If broadcast traffic is not suppressed, in case of heavy broadcast traffic, a great amount of network bandwidth is consumed, causing the network performance to deteriorate and even communication interruption.

Pre-configuration Tasks

Before configuring traffic suppression, connect interfaces and configure their physical parameters so that they can go Up physically.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run vsi vsi-name [ static ]

    The VSI view is displayed.

  3. Run suppression { inbound | outbound } enable

    Traffic suppression is enabled in the VSI.

  4. Run broadcast-suppression cir cir-value [ cbs cbs-value ] { uni-inbound | uni-outbound }

    Broadcast traffic over the VSI AC is suppressed.

  5. Run multicast-suppression cir cir-value [ cbs cbs-value ] { uni-inbound | uni-outbound }

    Multicast traffic over the VSI AC is suppressed.

  6. Run unknown-unicast-suppression cir cir-value [ cbs cbs-value ] { uni-inbound | uni-outbound }

    Unknown unicast traffic over the VSI AC is suppressed.

  7. Run commit

    The configuration is committed.

Checking the Configurations

After configuring traffic suppression, check the configurations.

Run the display traffic-statistics vsi vsi-name suppression uni command to check traffic suppression statistics in a VSI.
