This read-write truth value controls whether source and destination IP addresses 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 it enabled in typical routed IP environments since IP address diversity usually gives a good spread of traffic across aggregated links. For example, disabling this on a link carrying mostly non-IP or single-flow traffic would remove IP addressing from the hash calculation, relying instead on MAC or port-number fields.
