Configuration guidelines
Follow these guidelines when configuring a link aggregation group:

In an aggregation group, the port to be a selected port must be the same as the reference port in port
attributes, and class-two configurations. To keep these configurations consistent, you should configure
the port manually.
 Reference port: Select a port as the reference port from the ports that are in up state and with the same
class-two configurations as the corresponding aggregate interface. The selection order is as follows:
full duplex/high speed, full duplex/low speed, half duplex/high speed, and half duplex/low speed,
with full duplex/high speed being the most preferred. If two ports with the same duplex mode/speed
pair are present, the one with the lower port number wins out.

Port attribute configuration includes the configuration of the port rate, duplex mode, and link state.

For more information about class-two configurations, see “ Class-two configurations ”.
 To guarantee a successful static aggregation, ensure that the ports at the two ends of each link to be
aggregated are consistent in the Selected/Unselected state. To guarantee a successful dynamic
aggregation, ensure that the peer ports of the ports aggregated at one end are also aggregated. The
two ends can automatically negotiate the selected state of the ports.
 Removing a Layer 2 aggregate interface also removes the corresponding aggregation group. At the
same time, all member ports leave the aggregation group.
