CAUTION:
■ The following ports cannot be added to an aggregation group: destination
ports to be mirrored to, reflection ports to be remotely mirrored to, ports
configured with static MAC addresses, static-ARP-enabled ports, and
802.1x-enabeld ports.
■ Ports where the IP-MAC address binding is configured cannot be added to an
aggregation group.
Configuring a Manual
Aggregation Group
You can create a manual aggregation group, or remove an existing manual
aggregation group (after that, all the member ports in the group are removed
from the ports).
You can manually add/remove a port to/from a manual aggregation group, and a
port can only be manually added/removed to/from a manual aggregation group.
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.
