Setting Chassis Weights (chassis high-availability factors)
Each component in a Chassis has a quality weight factor, which sets its relative importance to overall Chassis health. For example, ports are more important than fans and are typically assigned a higher weight value. The Chassis grade is the sum of all component weight values. In a High Availability environment, the Chassis with the higher grade becomes Active and handles traffic. The grade for each component = (Unit Weight) X (Number of UP components)
To see the weight of each component:
> asg stat -v
Use set chassis high-availability factors to configure a component's weight.
