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 card or 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
Configuration Guide.

You can configure global or group-specific local-first load sharing for link aggregation. A link
aggregation group preferentially uses the group-specific local-first load sharing settings. If group-specific
local-first load sharing is not configured, the group uses the global local-first load sharing settings.
NOTE:
Local-first load sharing for link aggregation takes effect on only known unicast packets.
