Configuration guidelines

Follow these guidelines when you configure 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 is
performed in the following order: 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.
Port attribute configuration includes the configuration of the port rate, duplex mode, and link state.
•
For more information about class-two configurations, see
• To guarantee a successful static aggregation, make sure that the ports at the two ends of each link
to be aggregated are consistent in Selected/Unselected state. To guarantee a successful dynamic
