Setting the aggregation state of each member port
After a static aggregation group reaches the limit on Selected ports, ports attempting to join the group are put in Unselected state. This prevents traffic interruption on the existing Selected ports.

For more information about configuring the maximum number of Selected ports in a static aggregation group, see "Setting the minimum and maximum numbers of Selected ports for an aggregation group."
Any operational key or attribute configuration change might affect the aggregation state of link aggregation member ports.
