distribute-weight (interface view)

Function

Using the distribute-weight command, you can configure the load-balancing weight for an Eth-Trunk member interface.

Using the undo distribute-weight command, you can delete the configured weight for an Eth-Trunk member interface.

By default, the weight of an Eth-Trunk member interface is 1.

Format

distribute-weight weight-value

undo distribute-weight

Parameters

Parameter Description Value

weight-value

Specifies the weight of an Eth-Trunk member interface.

The value is an integer ranging from 1 to 8.

Views

Ethernet interface view, Layer-2 Ethernet interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

On an Eth-Trunk interface, you can load balance traffic among member interfaces according to the weights configured for the member interfaces.

The higher the weight of a member interface, the heavier the load over the member link. Therefore, you can run the distribute-weight command to configure a higher weight for a member interface so that the member link can carry a heavier load.

To restore the weight of a member interface to the default value, you can run either of the following commands in the Ethernet interface view:

  • undo distribute-weight, which restores the weight of a member interface to the default value

  • distribute-weight 1, which forcibly sets the weight of a member interface to 1, the default value

Prerequisites

To make the distribute-weight command take effect, ensure that an Eth-Trunk interface has been correctly configured and interfaces have been added to the Eth-Trunk interface.

Configuration Impact

The higher the weight of a member interface, the heavier the load over the member link.

If you run the distribute-weight command several times on the same interface, the latest configuration takes effect.

Precautions

A maximum of 8 member interfaces in an Eth-Trunk interface can carry out load balancing. The total weights of all member interfaces in an Eth-Trunk interface cannot be greater than 8.

When multicast traffic is transmitted over an Eth-Trunk interface, if the distribute-weight command is used to change the weight of a member interface, you need to run the shutdown and then undo shutdown commands to restart the member interface for the configuration to take effect.

Example

# Set the load-balancing weight of the member interface GE 1/0/1 of an Eth-Trunk interface to 3.
<sysname> system-view
[sysname] interface GigabitEthernet 0/0/1
[sysname-GigabitEthernet 0/0/1] distribute-weight 3
