Equal-cost Multi-path Routing (ECMP) Hashing Alternatives for
  IPv4/IPv6
 
 
  You can dynamically choose between the existing 
ECMP (Equal Cost Multi Paths) hash method ("default") and the
   “custom” hash method. Within each of these two hash methods, several hash algorithm options are
   available to vary traffic distribution among multiple equal-cost IP gateways.

Note   
Custom hashing
    method is not supported on the X440-G2 and X620 series switches.
To configure the hash method, use the following command:
  configure iproute sharing hash-method
        custom {hash-algorithm [xor | crc-16 | crc-32 [lower | upper]]}
