Configuring link aggregation load sharing algorithm and hash
seed settings
About link aggregation load sharing algorithms
Use the link aggregation load sharing algorithm and hash seed features to optimize traffic distribution
on aggregate links when the default load sharing mode is used. Each algorithm represents a CRC
calculation method and the hash seed is used in hashing.
You can use a load sharing algorithm and a hash seed individually or in combination to obtain the
optimal load sharing performance.
When you try each algorithm or algorithm and seed combination, use the
display counters
command to verify the load sharing result.
Restrictions and guidelines
Neither the link aggregation load sharing algorithm setting nor the hash seed setting takes effect on
per-flow load sharing.
Procedure
1. Enter system view.

2. Configure a link aggregation load sharing algorithm.
link-aggregation global load-sharing algorithm algorithm-number
By default, no algorithm is configured.
3. Configure a link aggregation load sharing hash seed.
link-aggregation global load-sharing seed seed-number
By default, no hash seed is configured.
Setting a hash offset to adjust the load balancing results on
link aggregations
About the load sharing hash offset
If undesirable traffic imbalance occurs on link aggregations, you can use this command to adjust the
load sharing results on link aggregations.
Restrictions and guidelines
Misuse of this feature causes unbalanced traffic distribution. Make sure you are fully aware of the
impacts of this feature when you configure it on a live network.
Procedure

2. Set a hash offset to adjust the load sharing results on link aggregations.
link-aggregation global load-sharing offset offset-value
By default, no hash offset is configured for load sharing on link aggregations.
