Configuring per-flow load sharing algorithm settings for
Ethernet link aggregation
Configure the per-flow load sharing algorithm and algorithm seed to optimize traffic distribution on
aggregate links based on existing per-flow load sharing settings. You can set only the algorithm or the
algorithm seed, or both. You can combine an algorithm with different algorithm seeds to obtain different
effects.
This feature does not take effect on per-flow load sharing that uses the following traffic classification
criteria:
• Source IP address.
• Destination IP address.
• Source MAC address.
• Destination MAC address.
