reference port?
Meanwhile, the system with the higher system ID, being aware of the aggregation state changes on the
remote system, changes the aggregation state of its ports accordingly.
z Because any port attribute or class-two configuration change on a member port may cause the
aggregation state of the port and other member ports to change and thus affect services, it is
recommended that you do that with caution.
z In a dynamic aggregation group, when the aggregation state of a local port changes, the
aggregation state of the peer port also changes accordingly.
