Required.
By default, an aggregation group
uses the global link-aggregation load
sharing criteria.
Set the following group-specific load sharing criteria:
• Source IP address
• Destination IP address
• Source IP address and destination IP address
• Source MAC address
• Destination MAC address
• Destination MAC address and source MAC address
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 all member ports on the ingress card or switch rather than all
member ports.
When you aggregate ports on different member switches in an IRF virtual device, you can use local-first
load sharing to reduce traffic on IRF links, as shown in Figure 13. F
or more information about IRF, see the
IRF Configuration Guide.
