Load sharing criteria for link aggregation groups
In a link aggregation group, traffic may be load-shared across the selected member ports based on a set
of criteria, depending on your configuration.
Choose one of the following criteria or any combination for load sharing:
MAC addresses
•
IP addresses
•
Alternatively, configure the system to perform per-packet link aggregation.

Configuration guidelines
Removing an aggregate interface also removes the corresponding aggregation group. At the same time,
all member ports leave the aggregation group.
You cannot assign a port to a Layer 2 aggregation group if any of the features listed in
configured on the port.
