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

the ingress switch
To enable local-first load sharing for link-aggregation:

Enabling link-aggregation traffic redirection
CAUTION:
Link-aggregation traffic redirection only applies to dynamic link-aggregation groups.
To prevent traffic interruption, enable link-aggregation traffic redirection on devices at both ends of the
aggregate link.
To prevent packet loss that can occur at a reboot, disable both MSTP and link-aggregation traffic redirection.
The link-aggregation traffic redirection function can redirect traffic between IRF member switches for a
cross- -device link-aggregation group. Link-aggregation traffic redirection prevents traffic interruption when
you reboot an IRF member switch that contains link-aggregation member ports. For more information
about IRF, see IRF Configuration Guide.
