multicast-suppression cir cbs (VSI view)

Function

The multicast-suppression cir cbs command enables the multicast suppression function on the VSI.

The undo multicast-suppression command disables the multicast suppression function on the VSI.

By default, the multicast traffic function is disabled on a VSI.

Format

multicast-suppression cir cir-value cbs cbs-value

undo multicast-suppression

Parameters

Parameter	Description	Value
cir cir-value	Specifies the CIR, that is, the allowed rate at which traffic can pass through.	The value is an integer that ranges from 0 to 10000000, in kbit/s.
cbs cbs-value	Specifies the CBS, that is, the traffic that can pass instantly, or the depth of the first token bucket.	The value is an integer that ranges from 10000 to 4294967295, in bytes.

Usage Guidelines

Usage Scenario

On a VPLS network, the broadcast, multicast, and unknown unicast packets are transmitted in broadcast mode. If large quantities of multicast packets are on the VPLS network, the device has to make a lot of copies of these multicast packets, which wastes bandwidth and resources, and degrades the performance of the system. You can run the multicast-suppression cir cbs command to suppress the multicast traffic in the VSI. The rate of multicast traffic on the VPLS network is limited.

Prerequisites

A VSI has been created using the vsi vsi-name [ auto | static ] command.

Example

# Set the CIR to 100 kbit/s and the CBS to 18800 bytes for the multicast traffic that can pass in VSI1.
