multicast-suppression (interface view)

multicast-suppression (interface view)

Function

The multicast-suppression command sets the maximum traffic volume of multicast packets that can pass through an interface.

Using the undo multicast-suppression command, you can cancel the rate limit for multicast traffic on an interface.

By default, multicast traffic is not suppressed on an interface.

Format

multicast-suppression packets packets-per-second

undo multicast-suppression

Parameters

Parameter

Description

Value

packets packets-per-second

Specifies the rate limit in number of packets per second (pps).

The value is an integer, in pps. The value range is as follows:
  • GE interface: 0 to 14881000

Views

GE interface view, MultiGE interface view, XGE interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

When an increasing number of multicast packets are transmitted on a network, more network resources are occupied and services are affected.

To prevent broadcast storms, you can use the multicast-suppression command to set the threshold of multicast traffic that an interface allows to pass through. When the multicast traffic volume exceeds the threshold, the system discards the excess multicast packets to control the traffic volume of multicast packets to a proper range.

Example

# Set the rate limit for multicast traffic to 21600 pps on GigabitEthernet 0/0/1.
<Huawei> system-view
[Huawei] interface gigabitethernet 0/0/1
[Huawei-GigabitEthernet0/0/1] multicast-suppression packets 21600
