that, all the member ports will be removed from the group).
For a manual aggregation group, a port can only be manually added/removed to/from the manual
aggregation group.
Follow these steps to configure a manual aggregation group:

changes may be: changing from dynamic or static to manual, and changing from dynamic to static;
and no other kinds of type change can occur.
