A strategy for preventing hash polarization is to configure different hash seed values that are used by the CRC versions of the custom algorithms on link aggregated group (LAG) switches. With different hash seeds used on neighboring switches, hash polarization can be prevented while maintaining otherwise identical distribution algorithms.
ExtremeXOS 30.1 now provides the ability to configure hash seed values.
The following show commands are changed to display custom hash seed information:
show sharing
show port sharing
