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
Alternatively, you can let the system automatically choose link-aggregation load-sharing criteria based
on packet types (Layer 2, IPv4, or IPv6 for example).
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.

You can choose to create a Layer 2 or Layer 3 link aggregation group depending on the ports to be
aggregated:
•
To aggregate Layer 2 Ethernet interfaces, create a Layer 2 link aggregation group.
•
To aggregate Layer 3 Ethernet interfaces, create a Layer 3 link aggregation group.
