Load-Sharing Criteria For Link Aggregation Groups - HP 3100 Series Configuration Manual

Figure 9 Setting the state of a member port in a dynamic aggregation group
Meanwhile, the system with the higher system ID, which has identified the aggregation state
changes on the remote system, sets the aggregation state of local member ports as the same as
their peer ports.
A dynamic link aggregation group preferably sets full-duplex ports as the Selected ports, and will set
one, and only one, half-duplex port as a Selected port when none of the full-duplex ports can be
selected or only half-duplex ports exist in the group.
When the aggregation state of a member port changes, the aggregation state of its peer port also
changes.
After the Selected port limit has been reached, a port assigned to the dynamic aggregation group is
placed in Selected state if it is more eligible for being selected than a current member port.
The port assigned to the dynamic aggregation group after the Selected port limit has been reached is
placed in Selected state if it is more eligible for being selected than a current member port.

Load-sharing criteria for link aggregation groups

In a link aggregation group, traffic can be load-shared across the selected member ports based on a
set of criteria, depending on your configuration.
