This read-write truth value controls whether TCP/UDP source and destination port numbers are included as hashing inputs when the switch load-balances traffic across the physical links of a static link aggregation (LAG) group; it is enabled by default. Admins keep this enabled to get finer-grained load balancing across multiple flows between the same pair of IP addresses, since port numbers add extra entropy to the hash. For example, two servers exchanging many distinct TCP sessions would have their traffic spread more evenly across LAG member links when this object is enabled versus relying on IP addresses alone.
