Function

The hash index hash-index command configures a hash index.

The undo hash index command deletes a hash index.

By default, no hash index is configured.

Usage Guidelines

Usage Scenario

When symmetrical load balancing and symmetrical load balancing compensation are configured, to adjust the order in which trunk member interfaces are delivered, run the hash index command to configure hash indexes for the member interfaces.

Prerequisites

Symmetrical load balancing or symmetrical load balancing compensation has been configured using the load-balance symmetric-hash [ complement ] command.

Precautions

When configuring symmetrical load balancing, you must note the following:

The values of hash-index on both devices should be consistent.
The weight of the same member interfaces should be consistent to ensure that the load balancing result is consistent.
When not both interfaces on the two ends are Up, the load balancing result is not consistent.
The master/standby trunk cannot ensure that the load balancing result is consistent.

Example

# Set the hash index to 1 for a trunk member interface.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/0
[*HUAWEI-GigabitEthernet0/1/0] hash index 1
