Enabling local-first load sharing for link aggregation
About 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 slot.
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 6 . For more information about IRF, see
Virtual Technologies Configuration Guide .
