Configuring Link Aggregation - HP V1905 Series Getting Started Manual

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.
Static LACP Aggregation
2.
A static LACP aggregation group is also manually created. All its member ports are manually added and
can be manually removed (this prevents the system from automatically adding or removing ports from the
group). LACP is enabled on each of the member ports in the static aggregation group. When you remove
a static aggregation group, all the member ports in the up state form one or multiple dynamic aggregations
with LACP enabled.
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 receive and send LACP protocol packets.
 Only the selected ports can receive and send 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 an up state, the system determines the port with

the following settings being the highest as the master port (in descending order): 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 ports, 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.
The system sets the ports with basic port configuration different from that of the master port to

unselected state.
There is a limit on the number of selected ports in an aggregation group. Therefore, if the number of

the selected ports in an aggregation group exceeds the maximum number supported by the switch,
those with lower port numbers operate as the selected ports, and others as unselected ports.
