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 card or switch rather than all member
ports.
When you aggregate ports on different member switches in an IRF fabric, you can use local-first load
sharing to reduce traffic on IRF links, as shown in Figure 11 . For more information about IRF, see IRF
Configuration Guide.

Enabling link-aggregation traffic redirection
The link-aggregation traffic redirection function can redirect traffic between cards or IRF member switches
for a cross-card or cross-device link aggregation group. Link-aggregation traffic redirection prevents
