Enabling Local-First Load Sharing For Link Aggregation; Configuring Per-Flow Load Sharing Algorithm Settings For Ethernet Link Aggregation - HP 6125XLG Configuration Manual

Enabling local-first load sharing for link aggregation

Use the local-first load sharing mechanism in a multi-device link aggregation scenario to distribute traffic
preferentially across member ports on the ingress card or device rather than all member ports.
When you aggregate ports on different member devices in an IRF fabric, you can use local-first load
sharing to reduce traffic on IRF links, as shown in
Configuration Guide.

Any Selected ports on the
ingress switch?
Packets are load shared only
across the Selected ports on the
ingress switch
To enable local-first load sharing for link aggregation:
Step
1. Enter system view.
2. Enable local-first load sharing
for link aggregation.
Configuring per-flow load sharing algorithm settings for
Ethernet link aggregation
This feature is available in Release 2406P03 and later versions.
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:
The egress port for a traffic flow is an
aggregate interface that has Selected
ports on different IRF member switches
