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
