Usage Guidelines

Usage Scenario

There are three types of hash algorithms to implement traffic load balancing.

In two-level load balancing, hash algorithms cannot be configured the same for the first- and second-level load balancing on the router. If they are configured the same, the second-level load balancing does not take effect.

Configuration Impact

The load-balance hash-arithmetic command is cyclic in nature, and only the latest configuration takes effect. After the command is configured, the new hash algorithm takes effect on the interface board to perform traffic load balancing.

Precautions

In VS mode, this command is supported only by the admin VS.

Example

# Specify the hash algorithm to be random on the interface board.
