Configuring a Dynamic Aggregation Group
To guarantee a successful dynamic aggregation, ensure that the peer ports of the ports aggregated at
one end are also aggregated. The two ends can automatically negotiate the aggregation state of each
member port.
Follow these steps to configure a dynamic aggregation group:
