configuration (speed, duplex, basic configuration, management Key) of the ports to be
aggregated.
After the dynamic aggregation port enables LACP protocol, the management Key is 0 by
default. After the static aggregation port enables LACP, the management Key of the port is the
same with the ID of the aggregation group.
For the dynamic aggregation group, the members of the same group have the same operation
Key, for the static aggregation group, the ports of Active have the same operation Key.
The port aggregation is that multi-ports are aggregated to form an aggregation group, so as to
implement the out/in load balance in each member port of the aggregation group and provides
the better reliability.
12.2.1 Static LACP Aggregation
Static LACP aggregation is enforced by users configuration, and do not enable LACP protocol.
When configuring static LACP aggregation, use "on" mode to force the port to enter the
aggregation group.
12.2.2 Dynamic LACP Aggregation
1. The summary of the dynamic LACP aggregation
Dynamic LACP aggregation is an aggregation created/deleted by the system automatically, it
does not allow the user to add or delete the member ports of the dynamic LACP aggregation.
The ports which have the same attribute of speed and duplex, are connected to the same
device, have the same basic configuration, can be dynamically aggregated together. Even if
only one port can create the dynamic aggregation, that is the single port aggregation. In the
dynamic aggregation, LACP protocol of the port is at the enable state.
2. The port state of the dynamic aggregation group
In dynamic aggregation group, the ports have two states: selected or standby. Both selected
ports and standby ports can receive and send LACP protocol, but standby ports can not
forward the data packets.
Because the limitation of the max port number in the aggregation group, if the current number
of the member ports exceeds the limitation of the max port number, then the system of this end
will negotiates with the other end to decide the port state according to the port ID. The
negotiation steps are as follows:
Compare ID of the devices (the priority of the system + the MAC address of the system). First,
