Required
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.
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.
You cannot enable LACP on a port which is already in a manual aggregation group.
Follow these steps to configure a dynamic LACP aggregation group:
