190 CHAPTER 23: LINK AGGREGATION CONFIGURATION
Note that:
1 When creating an aggregation group:
■ If the aggregation group you are creating already exists but contains no port,
its type will change to the type you set.
■ If the aggregation group you are creating already exists and contains ports, the
possible type 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.
■ When you change a dynamic/static group to a manual group, the system will
automatically disable LACP on the member ports. When you change a
dynamic/static group to a manual group, the system will remain the member
ports LACP-enabled.
2 When a manual or static aggregation group contains only one port, you cannot
remove the port unless you remove the whole aggregation group.
Configuring a Static
LACP Aggregation
Group
You can create a static LACP aggregation group, or remove an existing static
aggregation group (after that, the system will re-aggregate the original member
ports in the group to form one or more dynamic aggregation groups.).
You can manually add/remove a port to/from a static aggregation group, and a
port can only be manually added/removed to/from a static aggregation group.
