number supported by the device, those with lower port numbers operate as the
selected ports, and others as unselected ports.
Among the selected ports in an aggregation group, the one with smallest port number
operates as the master port. Other selected ports are the member ports.
III. Requirements on ports for manual aggregation
Generally, there is no limit on the rate and duplex mode of the ports (also including
initially down port) you want to add to a manual aggregation group.

1.2.2 Static LACP Aggregation Group

I. Introduction to static LACP aggregation
A static LACP aggregation group is also manually created. All its member ports are
manually added and can be manually removed (it inhibits the system from
automatically adding/removing ports to/from it). Each static aggregation group must
contain at least one port. When a static aggregation group contains only one port, you
cannot remove the port unless you remove the whole aggregation group.
LACP is enabled on the member ports of static aggregation groups. When you remove
a static aggregation group, all the member ports in up state form one or multiple
dynamic aggregations with LACP enabled. LACP cannot be disabled on static
aggregation ports.
II. Port status of static aggregation group
A port in a static aggregation group can be in one of the two states: selected or
unselected.
Both the selected and the unselected ports in the up state can transceive LACP
protocol packets.
Only the selected ports can transceive service packets; the unselected ports
cannot.
In a static aggregation group, the system sets the ports to selected or unselected state
according to the following rules.
Among the ports in an aggregation group that are in up state, the system
determines the master port with one of the following settings being the highest (in
descending order) as the master port: full duplex/high speed, full duplex/low speed,
half duplex/high speed, half duplex/low speed. The ports with their rate, duplex
mode and link type being the same as that of the master port are selected port,
and the rest are unselected ports.
The ports connected to a peer device different from the one the master port is
connected to or those connected to the same peer device as the master port but to
a peer port that is not in the same aggregation group as the peer port of the master
port are unselected ports.
