LAG port hash-weight

The LAG port hash-weight allows the customization of the flow hashing distribution between LAG ports by adjusting the weight of each port independently for both same-speed and mixed-speed LAGs.

The LAG port hash-weight capabilities combined with the support for additional mixed-speed LAG combinations as compared to port-weight-speed make the LAG port hash-weight a more flexible feature.

Common rules for LAG port hash-weight:

• The configured hash-weight value per port is ignored until all the ports in the LAG have a hash-weight configured.

• The hash-weight value can be set to port-speed or an integer value from 1 to 100000:

  • port-speed

    This allows the user to implicitly assign a hash-weight value based on the physical port speed.

  • 1 to 100000

    This value range allows for control of flow hashing distribution between LAG ports.

• The LAG port hash-weight value is normalized internally to distribute flows between LAG ports. The minimum value returned by this normalization is 1.

• The LAG port hash-weight defaults to the port-speed value when unconfigured.

The hash-weight values using port-speed per physical port types are shown in Table: Port types and speeds.
