80 CHAPTER 15: LINK AGGREGATION CONFIGURATION
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.
When adding Ethernet ports to an aggregation group:
■ You cannot add the following types of ports into an aggregation group: mirroring
port, port with static MAC address configured, port with static ARP configured,
port with 802.1x enabled.
■ 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.
When you add an LACP-enabled port to a manual aggregation group, the system will
automatically disable LACP on the port. Similarly, when you add an LACP-disabled
port to a static aggregation group, the system will automatically enable LACP on the
port.
