Load-sharing criteria for link aggregation groups
In a link aggregation group, traffic can be load-shared across the selected member ports based on a set
of criteria, depending on your configuration.
You can choose one of the following criteria or any combination for load sharing:
• Source/Destination MAC addresses
• Source/Destination service port numbers
• Ingress ports
• Source/Destination IP addresses
Configuration restrictions and guidelines
Follow these guidelines when you configure a link aggregation group:
• To ensure stable aggregation state and service continuity, do not change port attributes or class-two
configurations on any member port. If you must, make sure you understand its impact on the live
network. Any port attribute or class-two configuration change might affect the aggregation state of
link aggregation member ports and ongoing traffic.
Avoid assigning ports to a static aggregation group that has reached the limit on Selected ports. These
ports will be placed in Unselected state to avoid traffic interruption on the current Selected ports.
However, a device reboot can cause the aggregation state of member ports to change.
