operation key. The management key of an LACP-enabled dynamic aggregation port is
0 by default. The management key of an LACP-enabled static aggregation port is the
same as the aggregation group ID. In a dynamic aggregation group, the member ports
must have the same operation key. In manual and static aggregation groups, the active
ports have the same operation key.
7.1.3 Aggregation Types
Port aggregation can be divided into manual aggregation, dynamic LACP aggregation
and static LACP aggregation.

I. Manual aggregation and static LACP aggregation

Both manual aggregation and static LACP aggregation are configured manually, and
cannot be added or removed automatically by the system. A manual or static LACP
aggregation group must contain a member port at least. In the case of one port in an
aggregation group, the unique method for you to remove the port from the aggregation
group is to delete the aggregation group. By default, the system disables the LACP for
the manual aggregation port. You are prohibited to enable the LACP for the manual
aggregation port. By default, the system enables the LACP for the static aggregation
port. When a static aggregation group is removed, the member ports will form one or
more dynamic LACP aggregation groups with LACP enabled. You are prohibited to
disable the LACP for the static aggregation port.
In the manual and static aggregation groups, a port maybe in active or inactive state.
The port in active state can tranceive user service packets, but the port in inactive state
cannot. The active port with the minimum port number serves as the master port, while
others as slave ports.
In a manual aggregation group, the system sets the ports to active or inactive state
based on these rules:
z Based on the descending order of priority levels from full duplex/high speed, to full
duplex/low-speed, to half duplex/high speed and till half duplex/low speed, the
system sets the port with the highest priority to active state, and others to inactive
state.
z The system sets to inactive state the ports which cannot aggregate with the
master port, due to hardware limit (such as trans-board aggregation is forbidden).
z The system sets to inactive state the ports with basic configurations different from
the active port.
In a static aggregation group, the system sets the ports to active or inactive state based
on these rules:
z Based on the descending order of priority levels from full duplex/high speed, to full
duplex/low-speed, to half duplex/high speed and till half duplex/low speed, the
system sets the port with the highest priority to active state, and others to inactive
state.
