Step Command Remarks
3. Set the load sharing mode
for the aggregation group.
link-aggregation load-sharing
mode
{ {
destination-ip
|
destination-mac
|
destination-port
|
source-ip
|
source-mac
} * |
flexible
}
By default, the group-specific
load sharing mode is the same
as the global load sharing mode.
Enabling local-first load sharing for link aggregation
Use local-first load sharing in a multidevice link aggregation scenario to distribute traffic preferentially
across member ports on the ingress device.
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 Figure 11. Fo
r more information about IRF, see IRF
Configuration Guide.

To enable local-first load sharing for link aggregation:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enable local-first load
sharing for link aggregation.
link-aggregation load-sharing
mode
local-first
By default, local-first load sharing
for link aggregation is enabled.
Configuring link aggregation load sharing algorithm settings
To optimize traffic distribution on aggregate links, you can configure a link aggregation load sharing
algorithm and an algorithm seed. 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.
