• If multiple ports have the same port priority, duplex mode, and speed, the port that has been a
Selected port (if any) is chosen. If multiple ports have been Selected ports, the one with the smallest
port number is chosen.
• If multiple ports have the same port priority, duplex mode, and speed and none of them has been
a Selected port, the port with the smallest port number is chosen.
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 states of link
aggregation member ports and ongoing traffic.
