This option allows an operator to only include source parameters or only include destination parameters in the hash for inputs that have source/destination context (such as IP address and Layer 4 port). Parameters that do not have source/destination context (such as TEID or System IP for example) are also included in hash as per applicable hash configuration. The functionality allows, among others, to ensure that both upstream and downstream traffic hash to the same ECMP path/LAG port on system egress when traffic is sent to a hair-pinned appliance (by configuring source-only hash for incoming traffic on upstream interfaces and destination-only hash for incoming traffic on downstream interfaces).
