Note:
For a static LACP aggregation group or a manual aggregation group, you are
recommended not to cross cables between the two devices at the two ends of the
aggregation group. For example, suppose port 1 of the local device is connected to port
2 of the peer device. To avoid cross-connecting cables, do not connect port 2 of the
local device to port 1 of the peer device. Otherwise, packets may be lost.
1.2.3 Configuring a Dynamic LACP Aggregation Group
A dynamic LACP aggregation group is automatically created by the system based on
LACP-enabled ports. The adding and removing of ports to/from a dynamic aggregation
group are automatically accomplished by LACP.
You need to enable LACP on the ports which you want to participate in dynamic
aggregation of the system, because, only when LACP is enabled on those ports at both
ends, can the two parties reach agreement in adding/removing ports to/from dynamic
aggregation groups.
Note:
You cannot enable LACP on a port which is already in a manual aggregation group.
