Configuring VSI-based Traffic Suppression

Context

On a VPLS network, you can limit the rates of broadcast, multicast, and unknown unicast packets to:

Enhance traffic management and appropriately allocate user bandwidth.
Prevent traffic attacks and enhance network security.

You can flexibly control the processing of unknown multicast packets. For example, you can enable the device to discard unknown multicast packets in the IGMP-snooping over VPLS scenario.

Do as follows on the PEs on which the VSI broadcast traffic, multicast traffic, and unknown unicast traffic need to be suppressed.

Procedure

Run system-view
The system view is displayed.
Run vsi vsi-name
The VSI view is displayed.
Run broadcast-suppression cir cir-value cbs cbs-value
The broadcast traffic is suppressed based on VSIs.
Run multicast-suppression cir cir-value cbs cbs-value
The multicast traffic is suppressed based on VSIs.
Run unknown-unicast-suppression cir cir-value cbs cbs-value
The unknown unicast traffic is suppressed based on VSIs.
Run unknown-frame multicast { drop | broadcast }
The processing mode for received unknown frames is configured.
