Link Aggregation Configuration 113
n
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.
n
You cannot enable LACP on a port which is already in a manual aggregation
group.
n
Changing the system priority may affect the priority relationship between the
aggregation peers, and thus affect the selected/unselected status of member ports
in the dynamic aggregation group.
